...It's funny you mention Florida...
Florida isn't necessarily hotter than the northeast. Depends a lot on where you are in the state. Orlando, forget it. You'll cook. Marion county, too. But the Atlantic coast benefits from the effects of the Gulf Stream -- they help keep things warm in the winter, cooler in the summer. Miami, as such, has a record high of only 96. We've long since smoked that in the Boston area, with many triple digit occasions in my lifetime alone. Miami is humid from about June to September, though, in a way that we often aren't. In Florida, you don't get the occasional high pressure system to come in and blow everything out. It is humid every day in the summer.
That said, though, the weather that we had in PA this past weekend was more intense than what I generally experienced in Miami during the same time of year.
Waiting by the side of the road with Laura on the way home frome the Nationals gave me a great chance to work on my tan, though. It was great.
