knowing your gear is always your best idea! sit at home and put the tent up 5 or 6 times
pay attention to what your fingers are feeling ( does the poles go through sleves or does the tent clip to the poles ) also feel the type of material its made out of at these points close your eyes if it helps. count pole sections if poles are diffrent lengths keep you steaks in you pocket or somewhere you can find them.
i've had to set up my tent in the dark a lot when i forgot my headlamp on a smokey mountains trip
also it a good idea to know how to tie knots in the dark. figure 8, a figure 8 follow through, figure 8 on a bite, clove hitch, and half hitch are the most common i use. but it always helps to know a few more! this will help if you lose a steak and have to guy out to something!!
