Take a look at the SanDiego owners site!!
Not that we could match their enthusiam or environment, but what about a trial gathering at Reza's Restaurant, 5255 N. Clark, Chicago, say for brunch some Saturday around 11:30?
They have a parking lot at 5238 N. Clark where we could also gather for a "show and tell", (11:00 as it fills up,) and the restaurant has separate rooms for private gatherings.
Any interest, alternative locations or ideas?
(Maybe someone could research nearby charging stations.)
