We had a great morning at the U of M on our last day in the US. First we walked from the Radisson down to Coffman Union and had a shopping spree at the university bookstore there. Then we crossed the Mississippi River on the Washington Avenue bridge, first through the covered walkway so that the kids could see all the adverts painted by campus clubs. Although it was only midmorning, the heat in the walkway was incredible: my camera lens fogged up immediately and wouldn't let me take any clear pictures. Everyone was anxious to be outside again, so we power-walked to the opposite side. They noted the "shoe tree" on the West Bank, and then we turned around again and walked back across the Mississippi, and back to the Radisson. There we had a short breather, and in no time at all, it seemed, we were putting our suitcases on the bus to go to the airport.
