Crossing at the historic watertower, I turned eastward and started bearing down on the lake. My yet-to-grow-weary feet were now advancing me to Streeterville where more of Chicago's ever-growing population of stylish offices and condominiums were to be found. In view were Ontarie Center and modern classic Lake Point Tower. Beyond those stood a gallery of newer post-modern cousins. Courting the river and spanning a bridge, the architectural decades continued to alternate, revealing the giant white Amoco column, pointed Prudential tower and triangular Swiss Grand hotel.
