Oceano/Pismo dunes, Barstow to Slash X Cafe is fun (sand wash), Johnson Valley/Hammertown, California City, Randsburg... I love some of the trails in Gorman/Hungry valley but most are too tight for more than a quad. Badlands trail is my favorite there. Never been to Glamis. Soon!
Another for Paiute in UT! Thousands of miles of forest, rivers, lakes, streams, trails that are in streams, high snow caps, low valley river lands. Ride for weeks and you still won't see it all, it's just unbelievable there.
My Fav is H/M in West Virginia. Looking for new trails, so I pose this question. We are planning a 3 day ride at the end of the month. We are up in the air about traveling (Ohio) to Brimestone or Windrock. Those that have been to both, would you say it's worth the drive to the others in TN? We love to go fast in the trails, which most of the H/M allow us to open them up with out having to worry about mud! Which one would you spend 3 days riding?
