my one friend has an uncle who live in las vegas and he is going to visit him this summer and he asked me to go. he said that the glamis sand dunes are a 3.5 hour drive away and wants to go. i started looking into things and the info that i got says that glamis is only opened during fall and winter, is this true? i made a post at socalmotox.com and go 2 different answers, one said its only open fall and winter, and the other said they are open year round so i dont know who right. also, do any of you guys know if there are any places top rent quads and bikes? someone on socalmotox.com said there is a place that rents quads there, but i would prefer a bike. i am trying to get as much info. together as i can, so if any of you guys have any links regarding glamis, and quad/bike rentals it would be great.
