Southern Indiana has, with out question the fastest flowing single track I have ever ridden. Pictures never do trails justice, but I took some anyways. Rumor is there are more than 80 miles of trails in this immediate area. I highly recommend it to anyone traveling to the Indianapolis area.
Brown County state park has plenty of elevation to work with, which surprised me given it is in Indiana (1,500 feet of ascent in a 14 mile loop). A few climbs required 4 full size switch backs to get to the top. The vistas were pretty amazing.
