That's really cold....! If the temp drops around here it always seems to be dead calm, but I don't recall ever seeing single digits. I raise some animals for food, but become their full time servant when it gets below freezing. Imagine the struggle without power like a few generations ago.
Every year I say it's time to take a pair of the mechanic's gloves and lace them with nichrome wire and rechargeable batteries. I think that, plus a propane Mr Ready heater, a hot thermos and then it will become fun to cheat Mother Nature and get some comfortable flying in. The wind is a deal breaker though...then it's time to get out a kite.
