We made a flying trip to Boulder, Colorado in early April 2004. We were there to attend the 100th birthday celebration of Philip Carter. Boulder is nestled at the foot of the Rocky Mountains, northwest of Denver, and is home to Colorado University. In April there were many signs of Spring--on campus, along the walking trail beside Boulder Creek. There are great restaurants in and around Boulder, and the shopping looked good, but we didn't shop. Apparently rain is not unusual, and rain developed in the evening of the one day we spent in Boulder.
