I like 3 and 4 but I'm more of an "in the woods" kind of guy myself. now that I look again...I'd concentrate on # 4 myself. 3 of the wooded areas intersect at that point.

If the top of the map is North....then I'd say hunt a north or south wind and approach from the downwind side. Look for any trails in that area and set up down wind of those.

Good luck.
