I guess you didn't see the 22 of us Model S owners who showed up at the Hope Supercharger for a BC Tesla Owner's Club event/rally back in April
Good thing club organizers arranged a wait list/signup sheet for charging while we all had lunch at Rolly's.
so far, that's the only time I've been to the Hope SC, and I know that doesn't count so I don't know how busy it is there on a normal day. but good thing the parking lot is big - I suppose they could expand the number of chargers there if demand ever required it.
