Speaking of gross water. . .
A couple of summers ago, we rode Splash three times in a row when DL first opened in the morning. I wore my Chacos. Some water splashed onto my feet. By 2:00, I had developed a horrible, oozing, crusty, itchy, cracking, bleeding rash on the top of my feet. . .but the skin under the sandal straps was perfectly clean. They looked like red scaly slimy feet from outer space, with the white strap lines from the Chacos perfectly delineated.
