If there are that many people in your woods, chances are someone else has been there in the past, just not when you were around! I agree try and cover your tracks, with snow, blood and drag marks it is pretty difficult. The bonus is those who are real avid hunter hit the wood real early and have their opening day spot picked out long in advance. The guys who are wandering around without a clue are also the ones who are usually last on scene with no real game plan. Hey if it happens like last year they will be too late, as you will have came and gone.

I don' t really worry about it to much, if it is free access land than what can you do about it anyway. I try to be discreet, never tell anybody details(except my hunting partners) and always be the first to arrive and leave.
