One of the interesting features about the Union Terminal is the perfect sound reflection in the main lobby area which is a dome. For example, you can stand at the base of the arch on one side of the main entry doorway and whisper. Someone standing on the other end of the arch on the other side of the main door way can hear you. Quite interesting. The whole room is a perfect echo chamber.
Sound is substantially magnified. Likely why they chose the venue.
The whole room is a perfect echo chamber. Which in a way suits Hillary and Warren since they and their leftist supporters are out of touch with the nation, and often hear nothing but their own foolish ideas repeated back to them by the sychophantic media.
