Me (2008 DRZ400s) and neighbor Rob (2005 WR450) riding some of the easier stuff at the FourMile OHV area in Chaffee County, CO, on the north side. This area is about 10k acres of riding with everything from easy sandy/desert riding to boulder-strewn technical courses for 4x4s with winches. It also includes several miles of alpine single trackl on the south side that comes with outstanding views of the Arkansas Valley, the Collegiate Peaks and more.
The video quality is only so-so. Video was taken with a tiny MUVI camera mounted to my helmet visor.
