A cart ski system for urging a cart along a granular support surface includes a cart that may be rolled along a support surface. The cart has a set of rear wheels and a set of front wheels. A pair of skis is provided and each of the wheels is positioned in a corresponding one of the skis. Each of the skis slides along the support surface when the support surface is comprised of a granular material thereby enhancing urging the cart along the granular material.

1. A cart ski system comprising: a cart being configured to be rolled along a support surface, said cart having a plurality of wheels, said plurality of wheels comprising a set of rear wheels and a set of front wheels;a pair of skis, each of said skis having corresponding ones of said wheels being positioned therein wherein each of said skis is configured to slide along the support surface when the support surface is comprised of a granular material thereby enhancing urging said cart along the granular material, each of said skis having a plurality of first, second, third and fourth apertures, each of said skis having a perimeter wall having a first lateral side and a second lateral side;a plurality of straps, each of said straps releasably engaging an associated one of said skis, each of said straps engaging an associated one of said wheels on said cart such that each of said straps retains said skis on said cart, each of said straps having a first end, a second end and a first surface extending therebetween; anda plurality of knobs, each of said knobs being coupled to said first surface of a corresponding one of said straps, each of said knobs being aligned with an associated one of said first and second ends of said corresponding strap, each of said knobs being extended through a selected one of said first, second, third and fourth apertures such that each of said straps is retained to form an arch extending between said first and second lateral sides of said corresponding strap, each of said straps engaging an associated one of said wheels on said cart to retain each of said skis on said cart. 2. The system according to claim 1, wherein each of said skis has a basal wall and said perimeter wall extending upwardly therefrom, said perimeter wall having a distal edge with respect to said basal wall to define an opening in each of said skis, each of said skis being longitudinally elongated such that each of said skis has a length being greater than a length between said rear wheels and said front wheels, said perimeter wall sloping outwardly from said basal wall wherein said perimeter wall is configured to frictionally engage the granular material thereby inhibiting said skis from sinking in the granular material. 3. The system according to claim 2, wherein said basal wall has a first surface and a second surface, said first surface having an associated one of said rear wheels and said front wheels being positioned thereon, said second surface being configured to frictionally engage the support surface, said first lateral side corresponding to each of said skis having said plurality of first apertures extending therethrough, said first apertures being spaced apart from each other and being distributed adjacent to said distal edge. 4. The system according to claim 3, wherein said second lateral side corresponding to each of said skis has said plurality of second apertures extending therethrough, said second apertures being spaced apart from each other and being distributed adjacent to said distal edge, each of said second apertures being aligned with an associated one of said first apertures. 5. The system according to claim 2, wherein said first lateral side corresponding to each of said skis has said plurality of third apertures extending therethrough, said third apertures being spaced apart from each other and being distributed adjacent to said distal edge, said plurality of third apertures being spaced from said plurality of first apertures. 6. The system according to claim 5, wherein said second lateral side corresponding to each of said skis has said plurality of fourth apertures extending therethrough, said fourth apertures being spaced apart from each other and being distributed adjacent to said distal edge, each of said fourth apertures being aligned with an associated one of said third apertures. 7. A cart ski system comprising: a cart being configured to be rolled along a support surface, said cart having a plurality of wheels, said plurality of wheels comprising a set of rear wheels and a set of front wheels; anda pair of skis, each of said skis having corresponding ones of said wheels being positioned therein wherein each of said skis is configured to slide along the support surface when the support surface is comprised of a granular material thereby enhancing urging said cart along the granular material, each of said skis having a basal wall and a perimeter wall extending upwardly therefrom, said perimeter wall having a first lateral side, a second lateral side and a distal edge with respect to said basal wall to define an opening in each of said skis, each of said skis being longitudinally elongated such that each of said skis has a length being greater than a length between said rear wheels and said front wheels, said perimeter wall sloping outwardly from said basal wall wherein said perimeter wall is configured to frictionally engage the granular material thereby inhibiting said skis from sinking in the granular material, said basal wall having a first surface and a second surface, said first surface having an associated one of said rear wheels and said front wheels being positioned thereon, said second surface being configured to frictionally engage the support surface, said first lateral side corresponding to each of said skis having a plurality of first apertures extending therethrough, said first apertures being spaced apart from each other and being distributed adjacent to said distal edge, said second lateral side corresponding to each of said skis having a plurality of second apertures extending therethrough, said second apertures being spaced apart from each other and being distributed adjacent to said distal edge, each of said second apertures being aligned with an associated one of said first apertures, said first lateral side corresponding to each of said skis having a plurality of third apertures extending therethrough, said third apertures being spaced apart from each other and being distributed adjacent to said distal edge, said plurality of third apertures being spaced from said plurality of first apertures, said second lateral side corresponding to each of said skis having a plurality of fourth apertures extending therethrough, said fourth apertures being spaced apart from each other and being distributed adjacent to said distal edge, each of said fourth apertures being aligned with an associated one of said third apertures;a plurality of straps, each of said straps releasably engaging an associated one of said skis, each of said straps engaging an associated one of said wheels on said cart such that each of said straps retains said skis on said cart, each of said straps having a first end, a second end and a first surface extending therebetween, anda plurality of knobs, each of said knobs being coupled to said first surface of a corresponding one of said straps, each of said knobs being aligned with an associated one of said first and second ends of said corresponding strap, each of said knobs being extended through a selected one of said first, second, third and fourth apertures such that each of said straps is retained to form an arch extending between said first and second lateral sides of said corresponding strap, each of said straps engaging an associated one of said wheels on said cart to retain each of said skis on said cart.
