Here's a couple to refine your list Webfoot-
*Save the rubber bands that produce depts use on broccoli bunches. You know the type; 1/4 inch wide, real thick and bright pink. They show up well in the dark, on the ground and in the bottom of your vest or backpack. I use them on box calls, decoy stakes, ground blinds and a myriad of other uses.
* Take the dowels to be used to prevent decoy spin, run one end in a pencil sharpener and paint them dark green or brown. Secure with a rubber band.
* Always have several folded up plastic grocery bags in your vest. (Wal Mart tumbleweeds). Again, a plethura of uses. If you come across a batch of morels or wild raspberrys, bag 'em up. Put one on your turkey's head with a rubber band to contain blood. Sit on one if you forget or loose your butt pad.
