I usually get where I can see pretty good at first when i do spot deer I will then move to 20 yards from their trail on the next hunt. at wheeler I look for fresh sighns because deer activity changes so often with pressure.
Another sighn that you have a good spot at wheeler is that you will find candy bar wrappers and soda bottles thrown around. if you find this you can rest assured that at least one person thought it was a good spot. I hate litter bugs.
