Just got back.......I'M HOOKED! The 'berg did great...still had some starting issues, but the power was more than enough to rip it up! I rode my friends 400EX quad some and it's a real toss up between that & a bike in the sand (I hate riding quads usually.) The quad was fun in the really deep sand, high banked trails where the bike was futile. And a quad is definitely more recreational than a bike, like for less aggresive types, kids, etc. But, in the open dunes and for jumping & climbing the bike is WAY more fun! Just unlimited air everywhere. It's like snowmobiling in the powder...which until now was the ultimate. What a rush carving the face of one of those huge sand bowls 4th gear pinned!!! Yes, it was hot. But, not nearly as uncomfortable as it is here in KC with the humidity. Dry as a bone down there. Riding from morning until 2pm was good, then back out at 6 pm until dark. Everyone down there, locals & riders alike were very friendly.
Thanks again for your help!
