The Maryland Independent Soapbox Federation & Incline Trials Society consistently boast one of the largest groups of racers to field a hill. With 15 or more carts racing side by side there is always action to behold as the front runners battle their way through the ranks. Sharing the East Coast is the New Jersey Underground Soap Box Federation and the Pittsburgh Illegal Soapbox Society who still make it out once in a while for the prestigious East Coast Challenge every year. The Wisconsin Underground Soapbox Society also runs their small group whenever they can sneak past the local fuzz (the only state in which soapboxing is actually illegal).
