Just because I think lots of people check this and not the events section: There is an event this Sunday which includes a car show, canyon drive, lunch and carwash. If you're a member of GGLC or LCOSC, it's all free. If you're not a member, it's $25 (the super fancy carwash is like $60 if you wanted to pay for it, plus the food is really good, so it's a bargain).
