As far as the colr goes....Y'all are bein wimps!!!
over winter break, out of sheer boredom, I'd find myself lighting up during the day, or evening after dinner, by my self, when it was anywhere between 20 to 4 degrees.
The 4 degree day was a bad choice, i could only sit outside for about 15 minutes at a time before i'd go warm my hands and come back out.
