Steve,
Maybe it's just my computer, but the picture you posted didn't show up for me. Anyway, you can start on the Curry Branch by driving up the gravel road to the South Shore campground of Phillips Lake. Go past the South Shore camp and the next one. You'll go up a hill and the road will split. Take a right, you'll cross a metal cattle guard about 200 feet in. Stay on that road, it is easily drive and rideable and is easy to follow for several miles. It starts to branch off after awhile, but if you use you best judgement and take the one that looks most like a main line grade you'll do fine. It's a really nice trip, you'll have fun.
Thanks Again, Taylor
