Rally Girl reports:
The crowd is marching along the narrow pavement on 22nd Street, shouting "Save Our Schools!"
Brett Banditelli from Teamster brother Rick Smith's show is passing out buttons that say, "Blackwater is to the military as vouchers are to education" and "Tom Corbett's Pennsylvania: Open for Business, Closed for Kids." Lots of handmade signs. Reporters are across the street.More updates to follow.
