The event that's received the most attention is the "tractorcade," which was moved from noon to 10am. "Tractors will take John Nolan Drive into Madison starting around 9:45 am and will circle the State Capitol once between 10:00 am and 11:00 am. Speakers will address the rally after the tractorcade, beginning around 12:00."
From noon to 3pm there's the "March on the Capitol" rally held by the AFT-Wisconsin union at the Martin Luther King, Jr. Blvd. entrance.
Starting at 1pm, you can run around the Capitol square as part of the "Run, Dems, Run!" protest run of 14 laps. They say this is 8 miles! But of course you don't have to run the entire 14 laps. The run starts at the State Street corner.
Art workers will march from the Overture Center to the Capitol at 2pm.
The big rally with the Wisconsin 14 begins at 3pm with music and speakers. Actor Tony Shaloub, whose sister is a teacher in his native Green Bay, is the keynote speaker. The Wisconsin 14 will be speaking as well as
