Quit yer gritchin'!
So ... if you want to stay "fresh", stay inside and get fat watching TV. If you want to ride, get out there and get used to it. I'm from Mississippi, and we have much worse heat/humidity than yoose guys up Nawth. The folks from Louisiana have it worse than we do, probably. We manage. You can too. Now go forth, take in electrolytes and water, and sweat while you conquer!
