The Texas Rangers were set to play the New York Mets on 6/14/08. Due to a good thunderstorm, the game was canceled. Not to waste a perfectly good Slip'n'Slide experience, a few Rangers went out and did a Tarp Slide, a 'la "Bull Durham" style :)
This is why I love baseball people. No other professional sport plays as long a season, and NO other sport allows the players to act like boys and for it to be ok.
