In PA with a bow it's only 50 yards. There are tons of guys that pull it off every year around me that use much less caution than you are talking about. They just walk in like they are supposed to be there and nobody pays them any mind. Heck they'll walk past posted signs and read them on the way in. Their view is, "if you look like you belong there, then you belong there."

Not for me though. Maybe I just like banging on doors.
