I am from the South myself, and I've yet to see what I would call a terribly hot summer in Central Indiana - but that is relative until you reach the numbers you mentioned. This will be my 10th summer here, so hopefully my luck will hold. Sunburn, however, I have to be very careful with as I do not tan.

I was just debating going to one spinning class a week this summer - but couldn't come up with a reason outside of inclement weather.
