My home has no A/C either. It's pissing hot here as well, though not as bad as it has been. It was well over a 100F last week, and right now its just in the 80s. Except my car is overheating and making a rattling sound as a result. Taking it to the shop so that that maybe my 45 mile drive to New Haven later won't cause the car to spontaneously explode.
