I live quite a ways away from Salinas, so I’m not very familiar with the town myself. But, I just took a quick look at a Facebook page for Salinas expats and found discussions and advertising about the following. An energy and massage center with different classes; Sailboat charters; plenty of restaurant raves including Smokin’ BBQ (where they appear to have live music at times), Sin…(where they just had a Super Bowl party), and Luccy’s; salsa dancing; a group of retired men that meet for lunch and conversation regularly; lots of day trips and musical events; and even a church on the beach.
I suspect that once you’re there and meet a few expats you’ll find even more things to do and great people to do them with!
