The two tractorcades to D.C. were big media events, but the protesting farmer who really got the cities attention was the peanut farmer who drove his John Deere tractor into a pond by the Malls reflecting pool in 2003.  He basically shut down the capital area for two days after the capital police got the impression that his tractor was loaded with explosives.  But as he explained at his trial, his comments about having an "organophosphate bomb" only referred to the two cans of Raid bug bombs that he had in the tractor cab.
