It's amazing the different receptions towns give to these G20 folks vs. the Tea Partiers. During the Tea Party we attended in NJ, the police closed off the main street and gave the TeaPartyExpress buses an escort into the town, all the police stood with the 3000 attendees, joking and speaking with everyone, all the businesses remained open (Fri. night) and the Municipal Hall (town hall) remained open for people to be able to use the facilities. I don't think Pittburgh is giving that type of reception to these crazies.
Also, it was such a different scene after the 9/12 Tea Party in DC where everyone cleaned up after themselves and left the area cleaner than when they got there. Contrast that to the inauguration of The One . . .
