One thing I have observed in tourney after tourney....little boys hitting the bathroom in their mat shoes....(now during the first two hours of the tourney the bathrooms are nice and clean..but never have I seen them stay that way)..usally by the third hour..there is a floor covered with urine, toliet overflow, and sink splash...I have never seen any child sanitize the bottom of their shoes after utilizing the facilities...I make my 46lb er stand on my feet now...but that dosen't work for my 110lb er ..so I have tried asking him to pull his shoes off between matches ..well that results in lost shoe after lost shoe..so I don't know what the answer is..but I would love to see every tourney sanitize the mats after warmups and offer the kids and refs sanitzer for their shoes...espically during cold and flu season...
