I don't mind cold until it's too cold. I'm good down to -10 before it seems unreasonable to me. (-40F windchill isn't unusual here) Have to say though I'd rather be too cold than have flies buzzing around my head. I must not taste too good to the biting variety though, rarely have to use bug dope of any sort and haven't had 5 mosquito bites in the last 5 years.
