Just drive out to the lakebed and kill it! Drifting, racing, it's all there! Hella fun trails on the edges of the lakebed, cheap great fun.

Great place for landsailing...the wind can push your sail cart at speeds over 50 miles an hour. When the wind is good there are a lot of people out here doing it on the weekends.
