OK, so I checked the link (thanks, Poetic Fool), and apparently, there isn't a meetup for Hubbers in Southern California (at least around my neck of the woods). Here is the link:
What I could do is start one for a local city (I'm near Oceanside/Carlsbad/San Clemente). After the meetup group is established, we could set a date and location to share coffee or wine in a suitable meeting place.
Anyone who would like to meet other Hubbers in other locations can do the same (but check if your city/nearby town has a meetup group first).
Personally, I would love to have a bonfire at the beach close by and have great discussions-- maybe closer to summer (weather permitting).
