Just started a couple of weeks ago; seems to be mostly word of mouth so far. Forums like 6speedonline, corvetteforum, etc. You can just google "cars and coffee richmond", or go to their
Facebook group. I think they are putting together an email list also.
It's held early Saturday mornings at the Starbucks at 5001 Huguenot Road ; that's the one just off the north end of the Huguenot bridge, right next to the Eye Institute. They had one on the 23rd and again this past Saturday (I heard about it from someone who was there), but I'm not sure about this coming Saturday.
