Whenever I hunt these types of terrain, I look for edges that intersect with another type of terrain, especially hardwoods, and then trails that come outat these points.
This is exactly how I approach the situation as well. We have several pine tree groves interspersed with hardwoods in my hunting area. In each case the easiest way to hunt them is to follow the trails that lead into them and then pick a likely ambush point for when the deer emerge.
