What is claimed is: 1. A backpack frame and support structure including: a pack frame assembly comprising a plurality of stays positioned relative to one another to form a polygon having at least four sides, said stays being semi-rigid and being connected by flexible connectors adjacent ends of the stays forming corners, said stays being captured by portions of the pack frame assembly to substantially limit longitudinal movement of the stays relative to the pack frame assembly, said pack frame assembly further including a member connected between at least some of the stays and operable to provide reinforcement between pairs of abutting stays to limit flexing of the flexible connector between each pair and limit enlargement of an included angle between abutting stays forming the included angle; at least one bag removably mounted to the pack frame assembly to form a backpack, said bag having a back panel portion with a plurality of spades extending in generally opposite directions therefrom; a hip belt assembly connected to the pack frame assembly; and a shoulder strap assembly connected to the pack frame assembly; wherein certain of said stays being positioned in a generally rectangular array and including generally upright stays and cross stays; wherein said stays each being positioned in a respective sleeve member and being captured between opposite ends of the sleeve member to prevent substantial longitudinal movement within a sleeve formed by a respective sleeve member; wherein the member includes a membrane having side marginal portions connected to the upright sleeve members and extending therebetween; wherein the member further includes a sheet of fabric comprising interconnected strands, said sheet of fabric having opposite major surfaces with one facing generally forwardly and one facing generally rearwardly and wherein the stays include a plurality of generally upright stays and a plurality of cross stays, including a generally upright stay positioned intermediate the outermost upright stays and being received in a respective sleeve member mounted to the membrane and at least one cross stay extending between outermost positioned upright stays at a position intermediate an upper and a lower cross stay and overlying the rearwardly facing surface forming a first gap therebetween; where said plurality of spades being at least semi-rigid and at least one of said plurality of spades being received in said first gap, said bag extending outwardly from the pack frame assembly and being suspended therefrom. 2. A backpack frame and support structure as set forth in claim 1 wherein the plurality of spades includes a first spade and a second spade, wherein the first spade is attached to and extends from an upper edge portion of the back panel portion and the second spade extends from a lower edge portion of the back panel portion, said first spade extending upwardly through said first gap and said second spade extending downwardly through a second gap, said second gap being formed between said lower cross stay and the rearwardly facing surface of said sheet of fabric. 3. A backpack frame and support structure as set forth in claim 2 wherein the at least one bag includes a plurality of bags removably mounted to the pack frame and positioned in superposed relationship.
