Dont make no difference whether it is legal or not, If you hunt over your feeder, your not going to get but a shot or two, and the deer will start to pattern you.
Find your trails going to, and from, your feeder, and set up about 100 yards from them. That way you will be legal, and you won't spook the deer off your feeder.
Deer get very leary of easy food, and even though they come to it readily, they will get REAL leary about coming to it once they feel threatened.
Mostly, they will change their pattern and come into your feeder when it is dark.
