Lol...on "real men" not using blankets and block heaters...I guess you never flew Garret/honeywell motors...below freezing we used blankets, block heaters, intake/exaust plugs and would often have a/c genorators parked on ramps at locations we would overnight if we could not get mains power (we carried about 100+ of extention cords and preplanned our parking with the FBO so we could plug in when possible)....GPU or not...different story with a PT6...great starting in the cold!!
