Since I am not attending, you can take my opinions and toss them out, but having once lived in Chicago and having family there I thought I would share some thoughts.

Most of the buildings that were the attractions for Capone and gangster buffs have been torn down. The tours would be fun but I think you will be driving by a lot places where buildings used to be. For instance, the hotels where Capone lived (Metropole and Lexington) are gone - the Lexington torn down at the time of the famous Geraldo special. The Hawthorne Inn, in Cicero, is also gone.

The garage from the St. Valentine's Day massacre is gone - there is an apartment building there now. There is a great restaurant called the Chicago Pizza and Oven Grinder Company across the street from the site of the hit. It has a unique kind of pizza that is more like a pot pie than deep dish pizza. The crust is on top. Rumor has it that the building the restaurant is in was used as a lookout prior to the hit.

You can still (or you could 7 years ago when I was there last) drive by the Capone house on S. Prarie Avenue. It's a pretty plain brownstone type house.

The Biograph Theater, where Dillinger was gunned down, is still there on Lincoln Avenue. My uncle took me past the house where Giancana lived in Oak Park, but I don't think I could find the place now.

Like I said, a lot of the old places are gone, but the fun of it would be to gather with Godfather fans and see the show they put on.
