I always take too much crap as well, I like to pack heavy at the start of the season to get into hiking shape quicker.
Binos, sp.scope, rifle and ammo (3 in the rifle, 7-9 extra), bone saw, 2 knives, sharpner, water/gaterade, little food, book, GPS, parachute cord, duct tape, flag tape, basic first aid stuff, rape whistle, deer calls, ass cushion, gaitors, rain gear, touque, gloves, wetnaps, (double as TP or help to clean up after a skinning) lots of game bags all (except the gun) in a pack on a packframe. By the end of the season I have thrown out the raingear unless it is actualy raining at the start of the hunt and I would be wearing the warmer clothing.
