Fire roads are all easy. Just make sure they're open- they close this time of year.
Cleghorn has bypasses for everything- but you don't always know you're on a tough section until you're on it. If in doubt- walk it first- or take the bypass around for a look see. There are a ton of Cleghorns runs posted here- just search "Cleghorn" for pics and video. There are some sections that are not easy and you might do some underbody scraping. Pinstriping is probable.
Gold Mountain is easy aside from two sections.
There is an easy run coming up on the 15th in Big Bear.
It isn't the best time of year- otherwise there is a run almost every other week. SoCal is a very active Jeep community- runs come up all the time so keep checking....
