You might be right, but I work in a NYC JHS and we have 125 teachers and 20 other staff. Most of them know me and that I went to the NYC Tea Party. As few as 10 agree with me and no one else here went. So the 25% could be true and still not indicate a massive turnout.
But we here know there was a massive turnout.

The best thing about these Tea Parties is that they are community based and go around the national media. How many Americans read about them on the front page of their local small town paper? How many Americans came into contact with one while going about their day?
My hat is off to you. You are the sort of folks that make freedom possible.
