yea we were down to those temps about a week or so ago and will get much worse in the weeks to come, the weather people are saying it'll be milder than normal this winter but when regular temps can hit in the -40c's milder than normal can mean alot of different things. I enjoy getting out for a smoke when I can now, with those temps coming and no heat for the deck I won't get out for much over the next couple months. Can't remember the specs on it but it's a cheap Bushnell I bought a couple years ago and only set up once or twice. Thought the kids would enjoy it but I can never find anything in the thing so someday I guess I should learn to use it.
