100 degrees and 50% humidity: Sauna City!
My wife, her sister and I were just in South Bend a couple of days ago, and we're driving her parents' van when suddenly we ran out of gas! Little more than half a mile from the gas station, I said screw it, I'll push the car there. BIG MISTAKE!!! I'm a SoCal boy, and I'm just not used to all that damn humidity, and 2 minutes into the push I'm dripping sweat. My wife's athletic but pregnant, so no way she could help, and her sister has a bad back and I didn't want to ask her.
But after a quarter of a mile pushing that behemoth of a van in 90 degree weather with a crapload of humidity, I friggin' needed help LOL. Her sis helped, and then a good sameritan (sp) got out of his car and lent a hand/saved my life. Gotta love midwesterners and their good hearts.
TT, go where there is water!!! Just came back from Burt lake up near Lake Michigan, and had a great time hanging in the lake, doing water activities that I can never do in the ocean. Got to visit Petoskey, and Harbor City as well, cool little places I'd never been. But since you're living much larger than me, the Caymans sounds like a winner! Have fun wherever you go!
