Check out the latest ASA news letter. No more none factory rear seats in UTV's! You now have to buy a Polaris or kawasaki 4 seater to carry more than 2 people when ready in the dunes. 2 thirds of people I go to Glamis with have rhinos with back seats they installed themselves. O ya and now everyone has to wear helmets even in UTV's and sand rails. Way to ruin the dunes California.
