Well, you definitely don't want to get into a pissing match with one of the orange army slobs. I approach public land based on pressure. If it gets hunted hard, I don't hunt it. I then find areas I like that are hard to get too or way off the beaten path.

I would slip into the place early in the morning and be listening for hunters whistling at you, etc. If you get there first there should be no problems from any other hunters, they should move on.
