Springfield Must-Sees?

[Susan Higginbotham]

Because of our recent move, I won't be able to make the upcoming Springfield tour, but I will be coming in mid-October for a short research trip. I'll be visiting the Lincoln house (of course), the old state house, and the railway depot, and I'll be seeing the outside at least of the Herndon firm and the Vachel Lindsay house (Ann Todd Smith's former digs). I plan to spend most of Monday in the presidential library, but I do hope to get to the cemetery to pay my respects.

Any other sites I should make every effort to see? I'll be staying downtown and will be on foot, and I will be under rather severe time constraints. There's always the possibility of a second trip, though.
