All 3 distinctly different, all 3 fun.
Mt. Kessler was the most familiar as to the type of trails one would find in KC. Back 40 was a blast, with big climbs and big descents with lots of flow. Slaughter Pen had more wooden obstacles than the other three combined with lots of drops and of course a downhill and dirt jump section.
Just a little over 3 hours from KC. Well worth the drive.
