I have two spots to charge at my garage, a NEMA 14-50 240/40amp and a Roadster HPC 240/70amp. I have a Roadster UMC for use with the 40 amp & Clipper Creek is bringing a portable J1772 that will also work with that for the Leafs/Coda. There will be a whiteboard for signups and amount of miles needed - I don't think it's going to be logistically difficult, since the Model S all have a nearby Supercharger. Just a few Leafs, a Coda, and a few Roadsters that will need top off miles to get back to the Bay area. I've worked out a plan with Tom Saxton to get his Roadster fully charged overnight - he can take mine and return it in the morning - if we run out of charge time.)
