I've always dropped mine if it's really wet.  I never saw the reasoning 
behind adding air, and thereby adding spring rate to the tire in slicker 
condidtions.......  You don't have the grip, and won't be deforming the 
tire as in the dry...........

I also know one reason given was so the tread "v"-ed out and supposedly cut 
through the water better.  I don't buy that either.  That is a minute 
amount, and I think would be more than lost by the stiffer sidewall.

JMHO though.  :-)  And you know me, I have plenty of those.
