I have something like 25 stands on the 775 acres I hunt and it can range from a couple hundred yard walk from where I park up to a 3/4 of a mile or better. Ive killed big deer within a couple hundred yards of my truck and Ive also done it a mile from my truck. I think it all depends on your situation. If there deer are traveling a long way and wont be near your stand for a couple of hours you probably can get away with parking a little closer. If your slipping into there bedroom and trying to go undetected you probably should consider walking for at least a few hundered yards, thats just my two cents.
