This has been an extremely hot summer here in Illinois.......and I'm sure in other places as well....we have central h & a/c - and I thank God each day for that blessing.. If I did not have central, I certainly would be looking for window units to make my days comfortable...but for those who choose not to, here's a tip......wet a mans handkerchief in cold water, wring out, and tie around neck...a primitive, but effective way to cool your body temp.
