there is no real "ozark trail". its just a culmination of several roads in a planned route per se.
We just competed in the Overland Challenge and had a blast. We did a scouting run a month ago, and were also out there in april for a fun trip, and did not hit any of the same trails at any time. The area is very vast and has lots of trails to do. I cant wait to go back and do some more exploring out there
