Just curious, do you mountain guys ever use, or even have a/c? I have a shaded house, do the windows open at night/closed in the day dance and usually make it to about this time to ever turn mine on. I didn't turn it on last year until that hot last week of May and haven't used it yet this year, and it doesn't look like ill need it through mid June at least. Most years I wait until June or later. You mtn peeps are usually anywhere from 5- 20 degrees cooler than me so...
