The RVators have a flyout on November 2nd:

“This Saturday the plan is Half Moon Bay, we plan on meeting on the ramp by 11:30, that is the ramp at the South end of the airport, not by the fuel pumps, then walking to the Restaurant. If it is foggy and we can’t get in the alternative will be Columbia at 11:30, the number for AWOS in HMB is 650-728-5649, if it’s not clear by 10:00 we will be headed to Columbia.”
