While I'd never call myself a professional photographer, I do feel like I have a decent eye and I've taken a few shots that I've enjoyed over the years. The 7 shots from Chicago were taken with an old 35mm camera.
The remaining shots were taken while Busch Stadium III was being built in downtown St. Louis with a digital camera. As the season wore down, Busch Stadium II was still standing while III was being built next door. The fans started to sign the pillars around the stadium, and it created a great visual of the old giving way to the new.
