I went through my file box from SB2002 to see what I might bring along this year. Maps, my home-made NG ID badge, WVPE schedule (Hi, Bob) and so on were easy.
But here's two things to bring up for newcomers and the oldies:
The Cord-Auburn-Duesenberg museum in Auburn, right up against the Ohio border, a bit north of Ft Wayne. is in the Cord factory building and it's considered one of the best single firm museums - probably because it's showroom is like it was in the 1930s, and you can even wander through the engineering dept and into Mr Cord's office! I've never heard anyone say they didn't like it. And I was kicking myself for all the times I drove so close to it coming from Boston to SB.
#2 is the Art Museum, in the Century Center, IIFC. The show was nice in 2002 and a cool break from the swap-meet heat.
