Part of the "heat and humidity" problem is our age. I was at the NSRA 50th a couple of years ago. It was a sea of grey, so many scooters you had to look both ways to enter a sidewalk. When we were "young and bullet proof" none of that was an issue. Matter of fact sitting through a serious rain storm was never an issue. As I age I find the willingness to put up with high temps, wet weather and long drives most unappealing. My wife can no longer ride in the 36 (late model Mustang seats) for anything more than 50 -60 mile runs unlike when we drove from Norfolk, VA to Columbus, OH non-stop. Now, having said all of that, I still love hitting the shop, building and driving but no longer enjoy the prospect of driving long distances to hit a car show.
