Any recommendations for a mild - medium trail in Southern California? A buddy of mine just got a new (old) truck running and we'd like to take it out for an run. Something that takes some skill to drive, but more than a graded fire road. (If we don't ease him into this, I'll never get him out again).
He just replaced/rebuilt the entire cooling system and wants to stay in the general vicinity of the Inland Empire.
Cleghorn, maybe, since it has easy with options of difficult?
