This is a track saved by my Garmin III+.
The track was laid during the last GerlachFest, Sept 13th 2003, while riding on the Black Rock Desert Playa, near Gerlach, Nevada.
"IBA" stands for IronButt Association, a bunch of ragmuffin long-distance motorcycle riders who on the whole are quite avid (and savvy) users of GPS navigation (see www.ironbutt.com.)
