Jesse,
we are at -16 right now with windchills hitting -35 to -40.when it gts this cold i dont shoot outside.
hell i wont even leave the house today.only time i leave the house when its this cold is to go to work.
if this keeps up,come monday i may call in sick.
i have heard of people breaking bows in extreme cold.cold air is dry air,the colder the drier it gets.
not to mention everything seems more brittle in the cold
