We had that same problem...There are some houses that border the property we lease. The people blatently hunt our stands in the front of the property, mostly during the middle of the week. We know this because we have found the following items:
1. cigarrette butts...no one in our group smokes.
2. Mickeys Malt liqour bottles...we don't drink that stuff.
3. A hat that does not belong to any of us.
SO...There are power poles that run the length of our property. We put up some old cameras on the power poles that we bought for a few $ that don't work. We hung signs on the perimeter that said no trespassing, property under surveilance. No more poachers that we are aware of.
VEGETARIAN...old indian word for bad hunter
