The Farmer Labor Tractorade of 53 tractors drives into Madison, Wisconsin on Saturday March 12, 2011. The farmers came to join a crowd of 80-100,000 (according to Madison Police - as reported by AP). The growing movement in Madison is protesting moves by "Tea Party" Gov. Scott Walker and Republican legislators to deny state workers their right to collective bargaining.
