i live in vegas and the only place to really ride anymore out here is nellis dunes, aka APEX its got some decent sand hills to shoot up but they are kinda rocky, really good places and things to jump and all goes on FOREVER! apex isnt really all sand. its a lot of like dirt
the other place i go riding is armagosa valley sand dunes, its about a hour and a half from vegas and consist of some good size bowls, comp hill, and some other hills that are softer than comp and steeper also
