For the uneducated:

1) That’s a Yamaha Rhino 700, not a buggy.
2) Based on what I can see, it’s had some work done. Aftermarket wheels, widened suspension… It’s worth more than the cars most of the people here drive.
3) This isn’t a trailer park. It’s almost certainly some kind of camp site at a sand dunes. Glamis, Waynoka, one of the others… its hard to tell. Notice the high dollar campers in the background and the sand around the road.
4) It’s incredible that they didn’t fold the roll cage in. If they hadn’t landed flat they probably would have.

This wasn’t a couple rednecks as the majority of commenters seem to think. Considering that it took place by sand dunes suggests California (closest thing the south has to dunes is Oklahoma) would be the most likely location. The fact they were wearing helmets would seem to reinforce that fact.
