we currently have a large NorCal and SoCal contingent and hold local rehearsals in Sacramento and Simi Valley and once a month we have a "camp" in central California. Those camps are typically a 6 hour block on a Saturday and we all carpool together. It makes for a long Saturday but it is lots of fun and we get a lot done. Get on the forum, drop us an email, and come on out to a rehearsal.
