Not sure either will be great racing, but I vote for the Hoosier 100. If you like memorabilia, the National Auto Racing Memorabilia Show (www.narmshow.com) is close to the track on Thursday evening, Friday and Saturday. (Disclaimer-I have nothing to do with the show, I just enjoy going there every year.) They have some Indy veterans, many of whom also drove midgets, sprints and dirt champs back in the day, available for autographs every year for what I think are very reasonable fees.
