On Monday, June 15, President’s Council Retreat-goers had the afternoon off to explore Chicago and then re-convened for dinner at Petterino’s, a local favorite known for its original drawings of actors who have performed in Chicago, seafood and steak, and mouth-watering raspberry chocolate tort. Geologist Harrison Schmitt, former U.S. Senator, astronaut, and Moon walker, took his audience on a trip to the Moon with a slide show of his Apollo landing and presentation on future space flight and energy diversity.
