I actually do know some very bad ass loops in that area. My parents had a home near the lake I used to ride right out of the driveway.
If you have fuel capacity of 100 miles or so , you can blaze the fireroad across the street from the gold strike and hit Lake Mojave, and Nelson Hills with as nasty of stuff as you dare.
Cross the pavement (Hwy 95)and over a couple small mountain ranges will get you to State Line for fuel.
Word of warning if going to Nelson Hills. If you see ANY KIND of hand written No Trespassing signs, or otherwise, stay the hell away. That small town has some loony tune gold prospectors that will shoot you on site.
If that's too hot for you, head on over to Pahrump and ride the endless horse trails at Mount Charleston. Clark and Nye County NV have an endless variety of riding to offer.
