This festival certainly isn't good, clean fun.
A mud festival in Westland, Mich., let kids play dirty on July 12. Children ages 12 and under had a chance to frolic in the muck at Wayne County's 2011 Mud Day, held at Hines Park-Nankin Mills Area, according to MyFoxDetroit.
The 24th annual Mud Day drew more than 1,000 kids -- not to mention 20,000 gallons of water and 200 tons of topsoil, The Detroit Free Press reports.
Thankfully for parents, the fire department hosed kids off afterward and handed out bags for muddy clothes, according to WOMC.
