It's tough when you gotta job/bills/mortgage/family etc. and aren't back by $$$ from communist/socialist/hate America front groups and politicians. All I know of is the Million American March, Sept. 6, 2004, Washington D.C. There are a lot of groups to join join if you look at the links on AmericanPatrol.com. That link list is getting big. Gotta keep up the pressure.
