I think it's probably a little scent lok and a little luck as most of hunting is luck. I had 3 yearlings come in down wind of me last friday and they didnt even acknowledge my presence. They walked about 35 yds behind my stand.

Oops, forgot to add that I dont own a scentlok suit and didn't even have time to take a shower as I was coming home from school. Just good old scent away.
