Great tips from everyone. The only other item I would offer is to look at fencerows to find the section of fence that is knocked down or easiest to cross from one side to the other. These areas will become a deer funnel as well. Also, you can create your own funnel by opening a section of fence or other terrain.
Those are good ideas, but just be careful about opening sctions of fence. Farmers build fences there for a reason, and opening them make cause some of their "reasons" to wander off.
Not a good thing to do if you want to continue hunting there! [:)]
