the best humidity cure in nyc is to get on the river. there is free kayaking at BPC, and great kayak tours at 23rd st and the Hudson. All the mucky, musty humidity smog just blows right off, plus it is usually about 5 degrees cooler. Im trying to work out a new triathalon: riding fixed, kayaking, and.... (so far all i can come up with is eating burgers, cuz i get hungry from the first two)
