If you want to find some runs in the area check with www.justruns.com
, they are planning runs all the time. Also, myjeeprocks.com has a forum and most of the people on it are from the socal area. They put together some fun runs as well. If you like, our local club geared 4 fun (geared4fun.com) schedules about once a month and newcomers are welcome to attend runs and/or monthly meetings. As for mudding, you'll not find a lot of that here in the desert that we live in. Perhaps you'll find some up in the mountains.
