Hook up with Reno4x4.com. Lots of places to go near Reno. Not all are official "trails", but lots of fun to go on day trips.
In Northern Nevada, the wheeling is what you make of it.
You are real close to the Rubicon Trail, and several ghost town treks are nearby.
Forest service roads are everywhere and you have a good starting point to chase the Emigrant Trail or the old Pony Express route.
The wife and I do a fair bit of rock hounding, fossil hunting and general prospecting. So the jeep is a means to get where we want to be.
Just be wise and go with a group if you can. Or leave your itenerary with a reliable person if you ever "go it alone". Breaking down is bad enough. Breaking down and no one knowing where you are or were going = BAD THINGS.
