My wife, son, and I stopped in this morning. This was our first time going to any sort of Tesla gathering...I have never seen so many Model Ss in one place before.
We got to meet and talk to some great folks...we showed up about the same time as a couple in a brown Model S, and as we all hopped out of cars, their first words to us were, "Here's another color they don't make any more!" (Mine is silver.) That was the first of several interesting conversations we had with other owners. My son spotted JPP's car and we introduced ourselves very briefly. Seeing all of these other Teslas (especially the customized ones) easily made my son's weekend...he probably could have stayed there the whole day.
I talked to some of the service folks because I wanted to see if I could transfer a service appointment I have scheduled in Fremont in a few weeks to Dublin. They're open now for service but they're still getting their stock of parts, business cards, etc. (The answer to my question was basically "yes" but I need to call them tomorrow to really arrange for it.)
