I watched a lot of it on CSPAN. It started late, and finished in the dark around 1900. I felt sorry for the units that were toward the end. And I felt for the Obamas. By the time the parade was over, I think they were the only ones left in the reviewing stand.
There was the band from the high school in Hawaii that Obama graduated from; the band representing the school of Michelle; THE Ohio State University Band - too bad there wasn't enough room to do Script Ohio.
