BALTIMORE - People ditched the porta pottys and brought their own toilets to Hampdenfest on Saturday.
The toilet-toting festival goers did not use the johns to "relieve" themselves -- but to race.
"This is my rookie year," said Matt Fouse.
Fouse is an artist who lives in Charles Village. Most people know him as The Baltimore Rat Czar .
The Baltimore Rat Czar is responsible for the stickers seen around Baltimore depicting a rat with the letters B-A-L-T on it. The bottom of the sticker reads "Charm City".
Fouse was asked by a friend to join the race this year. It was an offer he could not refuse because of the "absolute craziness and absurdity of it."
He used old car parts and items people donated to build his racer.
The last piece to add on was the brakes.
