I like this idea. I'd invite any and all EVs to participate. Only, I can't drive to S.F. How about Spokane, anyone? The Roadster is my daily driver, so people see it all the time. But a hundred Roadsters and Leaf's and DIY EVs all at once would be cool.
I'm in Northern Ca so Washington sounds good to me... If i do get a Performance version I want to put as many miles on it as I can. I love driving and it gets so expensive to go on long ICE trips!
Maybe downtown Seattle area for a city cruise? Spokane is 760+ mi from me, Seattle < 600mi I could stop in Grants pass and Salem and make it easily up there
