I was the one heading the meets up, but I have moved and don't know if there are any DSM meets still going down, you can try setting up one, find a good spot and offer to have others come out, start your own meet as it were.
RPM = Bradshaw & 50I do not believe there are enough DSMers near napa, but maybe you can start getting people together and start one, if not come out every so often to ours.
