The Louisville Mega Cavern located in Kentucky, is an underground bike park that recently added over 350,000 acres of features including, jumps, pump tracks, a dual slalom course, cross country and single track trails. To celebrate Diamondback's Eric Porter recently had an exclusive session at the park and came out with this cool edit combining his smooth style and this natural wonder. Now if you excuse me I am going spelunking around Jackson to see if I can find my own caves to help get me through this strange winter.
