I will also find the time and dates for the calico cleanup for you, It is a event everyone from So CAl needs to go to.Jim, I frequent both forums (and a few others as well). When Springfest time is nailed down, I'll post it as well. What I hadn't seen in the events are trail repairs or events that benefit/preserve the offroading community. If you or anyone is aware of those, let me know and I'll add it.
Someone said oil? Me! Me! (I don't do oversize).
