Sun dogs up here just mean it's f'ing cold. Carried mail on walking routes for 24 years. Hot or cold didn't bother the guys in the office. -28 to+ 110. Always easier to stay warm than cool off. For whoever asked about guns and shells in -0 never had any problems. The good thing is the colder it is the better the traction is. If the snow squeaks as you walk, and your mustache gets ice init the wild chill is -15 to - 20. Since it was sunny yesterday, even though the high was -9 there was a rooster pheasant feeding in the corn field west of the house. Heat is way worse than cold.
