Bows and cold - how cold is too cold?

[Griffith]

I'm shooting a laminate recurve (Martin Rebel) and live in Minnesota. It's a long winter, but we have a lot of mild winter temps that I enjoy being out in - teens on up.
Other than my own physical tolerance, is there a limit to how cold such a bow should be shot?
What about leaving it in the car in cold temps? How cold is too cold? (I know a hot car is death for a bow).

All clues appreciated - thanks!

You would have a better response if this was in powwow. I would like to see what others say on this also.
