There was one place I went to I'm particularly proud of having found. We call it Corpsewood around here, site of a grizzly, supposedly satanically oriented set of murders back in the late 70's. It's in Summerville, GA, roughly 45 minutes from my house. Very few people knew exactly where it was. Most of the people who knew about it didn't want to talk about it. That I found it in the late 90's, when the internet was in its infancy, I consider something of a minor achievement.
It's probably the single most middle-of-nowhere place I have ever been. The town itself is a few miles up the highway, and you have to travel a couple miles of logging trails on the ridge to reach it. Of course, it's not conveniently located next to one of said logging trails. At some point, you have to leave your car, and march about 400 yards in a specific direction in the woods to find it.
Three trips to Summerville, and 4 excursions on that ridge. That's how many times trips I took before I managed to find it.
...and now, thanks to the wonders of the internet, you can now watch at least a couple dozen people make the trip themselves on Youtube.
