There wasn't one in 2008, but there was one in 2007. It was pretty much for the same reasons, and the participants were considered "wackos".
Ah. I may stand corrected. But then, how many attended in 2007?
The turnout in 2007 was, I am sure, quite a bit less than this year but the outrage was no where near the level it is now. People are tired of the years of oppression thru taxes, and loss of liberties. Sure, there are folks who attended these rallies for various reasons, but the underlying rage over a government that is totally out of control remains a constant.
I have been classified a terrorist because of several beliefs that I choose to cling to. "Astroturf" you say ? I believe what you smell is the collective pot of oppression about to boil over.
