+1 on the kentucky windage
how about setting up a game of cat and mouse?
like the sniper instructors do or the E&E instructors do for pilots in training?
go in the woods somewhere, and have about 5-10 buddies come looking for you. but take it seariously, and dont let it become a game.
really think about the tracks you are leaving, and your camoflauge. A small part of a snipers training is actually shooting, many, many, hours are spent on camoflauge, moving without being seen, and escape & evasion. small things, like waiting for the wind to blow across a field of tall weeds before you belly crawl across it so you wont attract attention.
same goes for moving on dead leaves in the woods.
The human eye is best at detecting movement, solid colors and geometric shapes. do your best to eliminate all of these from your person, and your gear. also remember your outline. even if its pitch dark outside, you will be seen if you walk along the edge of a hill and your outline is visible aganst the skyline.
hell i know if i tryed that cat-and-mouse make believe E&E with with my buddies i would climb in a tall tree and watch them leave empty beer cans all over my frekin woods
