Well if you can get set up in the swamp thats where id be, but are they bedding in the pines? Well I would do what you said glass from that area maybe youll catch one coming from somewhere and get an idea on whats going on. The reason I said are they bedding in the pines is because around here they love the pines. At least you have aerial photos. watch the wind and go with your instinct. I think once you learn a little about the land youll key in on it. good luck
