We had another nice visit with graduate school friends today. Carl Renner was in my research group at MIT under Professor Greene. He finished his PhD two years before I did and went on for a long career with DuPont. He and Rene live in Wilmington which is only about 30 minutes away. We arranged to have a very nice lunch with them at Harry's Savoy Grill in Wilmington. The food was very good. We had a nice relaxing time and caught up on everything. Life is good.
