The Obamas walk along Pennsylvania Avenue following the inauguration. Almost 2 million people braved hours walking and standing in the cold with comments such as “after waiting 400 years, a few hours of cold don’t matter at all.” Others described passing through pedestrian tunnels and long underpasses on their way to the Mall. In those covered passages with great acoustics the crowds would start up a chant of O-BA-MA which echoed and reverberated wonderfully. Another person told of being on a subway car when the passengers spontaneously began singing Amazing Grace. What a day!
