Hi~ I'm in the Santa Cruz area as well. I run a youth polyamory discussion group in connection with a youth kink community. If you identify as kinky at all (really, I mean AT ALL), then I'd suggest checking out Fetlife, which is awesome for making connections with people and hearing about events in Santa Cruz, Monterey, and the Bay areas. Also, there's Meetup.com which has a Santa Cruz based polyamory group: http://www.meetup.com/Santa-Cruz-Polyamory/
Happy connection-seeking, and feel free to message me!
