Colm was a fantastic guide. His mastery of bringing to life histoical events made the entire tour an absolute joy. He was very personable and his clear enjoyment and excitement for Chicago History pulled all of us in. On our tour, he had a binder of photos and newspaper clipping that he compiled. That was impressive! It worked seamlessly into his narration, but also it was that extra cherry on top to exemplify his dedication. Loved it!
