Not sure if you've already traveled, but also check out the ham repeaters on Santa Catalina Island.
147.090+, no tone
448.900-, 110.9 (make sure to enable PL on receive because there is a co-channel uncoordinated repeater in San Pedro.)
To expand on LACo DCS, they also have a net on Mondays at 7pm on 147.270+, 179.9PL. Repeater is also on Mt. Disappointment, WA6ZTR repeater. This is where the county sheriff station/district hams check in.
