Can be great, it has been for me on a few occassions... Check out ohiosportsman.com. There are a couple of threads devoted to "deer camp" and WNF. There is a guy by handle of "coonskinner" that has an sort of open bowcamp, and is very willing to help a guy getting started in the area.
There are a ton of deer down there, but it can be hard narrowing down areas to get them in bow range. It just takes time to learn the areas/terrain.
As Sipsey Rvr said, the influx of out of state plates hunting (especially around Nelsonville) has been on the steady increase every year (the completed 33 connector didnt help).
The areas around Logan can get a little too crowded for me, but you just got to put in the time and scout a bunch of areas. Oh and George is right- disregard anything positive I might have said there are no deer in WNF! Good luck it is a beautiful area.
