RE: Backpacks....Fanny Packs?
Look at Wal mart. I bought one a couple years back in the hunting section for $25. I now use my turkey vest to carry my stuff but I use the backpack for carrying 3 trail cams, batteries, a little garden rake and some mock scrape materials. Actually I have 2 backpacks. My other has all my treestand equipment. You should have plenty of room.
