My plans are converging for crossing the country from Boston to LA in June. Thinking about staying in LA area for 3-4 days and catching some sights. Tentative plan is to base at RIR (Flabob) since it looks like a nice airport and the hotels nearby aren't too expensive. Many things we want to see are aviation-related and we can get there by plane (SMO, TOA, CNO, RIV). Question is, if we want to head downtown to the LA County museum and things like that, where's the best airport to park our Cherokee for the day with easy transportation? Looks to me like BUR with Uber is the quickest but pretty expensive all-around. Any thoughts?
