Well, downtown New Haven is a mockup of what it looked like in the 1950s (a lot of the old buildings are still standing, and have been touched up by the Hollywood pros). 50s-era cars line the street.
This past week, Harrison Ford, Calista Flockhart, Steven Spielberg, Kate Capshaw and Co. arrived at the airport where my uncle works (he says everyone, especially Spielberg and Capshaw, were very nice). Harrison's been spotted around the city and has been friendly with the residents who live nearby. He even eats in local restaurants, amongst the public (instead of say, being cooped up in his hotel room, or having the restaurants closed so he could eat in private).
Gah, I wish I could have made it to the auditions!
