Big City RVing

I'dt research on city by city basis posting here and other places looking for RV parks with good transportation access. I'm not acquainted with all cities, but here in CA there are locations favorable to seeing Los Angeles and San Francisco due to location near public transportation.

For example if I was looking to tour LA, I'd stay in Orangeland RV park in Orange CA. It is walking distance to metrolink and Amtrak station.
