What is claimed is: 1. A device for transporting a ladder having a plurality of equally spaced parallel rungs, said device comprising a frame having an upper end, a lower end, and defining a longitudinal axis extending from said upper end to said lower end, a pair of wheels rotatably mounted to said lower end for rolling said frame over a surface, a first hook and a second hook mounted to said upper end, said first hook and said second hook each having a fixed open end, said first hook spaced from said second hook, and said open end of said first hook oriented to an angle of about ninety degrees with said open end of said second hook wherein said open end of said first hook will receive a first rung of said ladder after which said open end of said second hook will receive a second rung and while said second rung is retained in said second hook said first rung will be locked in said first hook to thereby retain said ladder to said device, an arm extending from said upper end and generally perpendicular to said longitudinal axis, said first hook and said second hook mounted on said arm, said first hook having generally parallel side members and an end member joining a first end of each of said parallel side members and a second end of said parallel side members defining said first hook open end, said second hook having generally parallel side members and an end member joining a first end of each of said parallel side members and a second end of said parallel side members defining said second hook open, end, said side members of said first hook being generally parallel to said arm, and said side members of said second hook being generally perpendicular to said arm. 2. The device of claim 1 wherein said first hook member is a channel having parallel planar side portions, a transverse end portion, and a length that is a little less than a length of said first rung. 3. The device of claim 1 and further comprising a removable retainer for locking said second rung within said second hook while said removable retainer is in place and unlocking said second rung when said removable retainer is removed. 4. The device of claim 1 and further comprising a pivot between said frame and said arm wherein said arm is moveable from a first position generally perpendicular to said longitudinal axis and a second position generally parallel to said longitudinal axis, and a lock for locking said arm in said first position. 5. The device of claim 1 and further comprising a plate, an attachment for removably attaching said plate across an upper surface of said first hook and said second hook. 6. The device of claim 5 and further comprising a material on a surface of said plate having a high coefficient of friction to reduce the sliding of objects carried on said plate. 7. The device of claim 1 wherein said first hook and said second hook removably attached to said arm by bolts. 8. The device of claim 7 and further comprising a retainer bracket having a planar central surface and perpendicularly extending outer end surfaces, and said retainer bracket attachable to said arm in substitution for said first hook and said second hook. 9. The device of claim 7 and further comprising a second retaining bracket, said second retaining bracket having a planar central surface and perpendicularly extending outer end surfaces, and said second retaining bracket attachable to said arm spaced from said bracket. 10. The device of claim 1 wherein said first hook having generally parallel side members and an end member joining a first end of each of said parallel side members and a second end of said parallel side members defining said first hook open end, and said second hook having generally parallel side members and an end member joining a first end of each of said parallel side members and a second end of said parallel side members defining said second hook open end. 11. A transporting device comprising a frame having an upper end, a lower end, and defining a longitudinal axis extending from said upper end to said lower end, a pair of wheels rotatably mounted to said lower end for rolling said frame over a surface, an arm extending from said upper end, said arm having a first end and a second end, a pivot connecting said first end to said arm to said upper end wherein said arm is moveable about said pivot from a first position generally perpendicular to said longitudinal axis to a second position generally parallel to said longitudinal axis, a lock for selectively locking and unlocking said arm into said first position, and a retainer on said arm for retaining a long object wherein a operator can position said long object on said retainer and by controlling one end of said long object and transport said long object across a surface using said device while said arm is locked in said first position and can store said device while said arm is in said second position, an elongate first hook and an elongate second hook, a first attachment for removably attaching said first hook to said arm, a second attachment for removably attaching said second hook to said arm, and said second hook spaced from said first hook wherein said first hook will receive a first rung of a ladder and said second hook will receive a second rung of said ladder for transporting said ladder on said device. 12. The device of claim 11 and further comprising a retaining bracket, said retaining bracket having a planar central surface and perpendicularly extending outer end surfaces, and said retaining bracket removably attachable to said retainer. 13. The device of claim 12 and further comprising a second bracket having a central body and perpendicularly extending outer end surfaces, and said second bracket removably attachable to said retainer at a location spaced from said bracket. 14. The device of claim 11 wherein said first hook is a channel hook having parallel planar side portions, a transverse end portion, and a length that is a little less than a length of said first rung. 15. The device of claim 14 wherein said first hook has an open end and said second hook has an open end, said first hook attachable to said arm with said open end in a first orientation, and said second hook attachable to said arm with said open end in a second orientation about 90 degrees from said first orientation wherein said first and second hooks can receive rungs of a ladder and said rung received in said first hook cannot be removed therefrom while said second rung is retained in said second hook.
