JackIel440, I live south of you, straight west of Evansville, IN. about 75 mi. and we lucked out, maintained about 33 untill it stopped raining then the bottom dropped out, down to high teens. Right now it's snowing and the wind is howling out of the N - NW. Really wishing I would have just went and bought a factory OWB a month ago instead of starting a quest for materials to build my own, with this wind and temps the geothermal is running alot, today would have been one of those big energy savings days with a OWB. What is it those Cubs fans always say? "just wait till next year" LOL.
