Looking for jeep trail/fire roads/easy single track ride within about 90 minutes of Los Angeles (say from intersection 405/10 freeways.) A friend took me out to Gorman, and we had fun, but I kept dumping my bike on technical single tracks (DRZ400SM with Adv tires.) Also, I'd prefer to go somewhere, rather than ride in circles on the trails. Would like the alternative of covering some distance off-road, seeing some scenery, maybe camping at a destination and returning the next day. Some pavement OK. Was thinking up to 40 miles outbound or more, with maybe some side routes. Our bikes are plated. Any suggestions?
