Dirty and happy

Has your child ever comes home dirty, because he loves to walk through puddles and messing about in the mud? This is flowers! Go with him on "Dirty Day" in Michigan - an annual event attracts about 1000 children - he would be, where carousing. Children of all ages come to this event to run, lie and lie down in a mud puddle, the creation of which this year took 20,000 gallons of water and 200 tons of soil.
