EJS really isn't an event for the hardcore rock buggy crowd, as Todd said most of the trails being run are much more about the scenery and the event is about socializing with others. Now I'm not saying that the rock buggy crowd isn't into that too, but if you've built a buggy that is registered as an OHV, chances are good that you're looking to thrash against the rocks, and thats really not what EJS is all about. So as Marc suggested, your best bet would be to select a different time of the year to go down to avoid the crowds and check out a place like Area BFE.
I agree the buggy's can't really do the trails and it inconveniences the trail leaders and RR4W if they do attempt to join the trail rides, but that doesn't mean buggy's should stay away from EJS.
I go to Moab in my buggy for the challenge, the scenery and outside of EJS for the seclusion. Sounds to me like I have common ground with people who join the official trails, just like I have in the past.
Don't tell me we shouldn't go to EJS because I have a buggy. I've been going to EJS for many, many years now and every time I go I donate money directly to the RR4W Mud Fund. I used to go on the official trails and I have family that still does. I make it a point to not go on the official trails on the days that RR4W will be on out of respect.
I like you, you're a good person... but your attitude about this pisses me off. I'm just as comfortable on an easier going trail as I am on anything in BFE. It's not all about "bashing rocks", that's the stereotype that's hurting this sport/hobby.
