It is that time of the year, Socalxj from Yahoo groups is holding the 5th annual Socalxj Jamboree out at Stoddard Valley. There is trails available for every level of ability or build up. For directions and a map of how to get there check Here
It is March 12-14th A great way to meat other XJer's in Socal. No admission fee, it is totally free including camping. It is totally primative camping so bring water and supplies. It is also located about 15 to 20 minutes from Barstow so lodging is close for those who do not want to camp.
Hope to see ya there
