Ya thats the basis of it all, drink, drink, and umm...drink alot...ohh and there is usually lots of nice poon walking around everywhere. Night rides can be fun if you got a light, you can watch all the rails with massive caddy motor do wheelies up those hills, or just watch someone with a new truck like a h2, super duty, etc and wait for them to do something supid and tear up a 40K truck. The dunes can get quite big and you can catch some serious air on a bike out there.
Usually on big weekends robby gordon is out there with one of his trophy trucks and he can be a freakin nut the way he drives that thing. But its all fun, you have to be there to see how fun it is. Pictures do not do it justice at all. The dunes themselves are amazing too, things that you only see in pictures, and the night is crazy how many stars you can see. Which when you live in LA says alot. But its not for everyone, I like to go only a few times a year, the rest of the time I ride mostly track, or a bit of desert. (little sand)This isnt me but it shows how crazy dune jumping can get.
