Tonight I had to turn on my A/C for the first time this summer. It is muggy, with no wind. I just open the windows at nigh to cool down the house, but without the wind the house is too muggy to sleep. So I had to turn on the a/c. How many of you use a a/c? When did you turn it on for the first time this summer? My neighbor has had hers running since april. It is going now, and they are gone for 2 weeks.
