The fork hole is the hole of water you run into if you drive all the way down Scott's gulf road. Yes the 100 acre lake is billy branch lake on billy branch road. It isn't part of Bridgestone anymore. It is Firestone property. About 15 years ago BS/FS sold the state 10,000 acres. But kept 5,000. Since, the BS/FS wilderness area has added a few thousand more acres. Any Firestone property is lease only membership and not public land anymore.
