At Wing's suggestion, I checked out Daily Kos. Oh, boy! This is a blog, and pictures, from someone who was at the memorial event yesterday.
The third picture shows students during the day, outside the stadium, making a giant "peace chain", a series of connected links of paper notes of peace. I am sure, as they are all wearing red shirts, they must be student communists working for Obama.
