43 Farenheit is cold for Arizona? It's 19 F in Chicago right now (and dropping) with a 25 mph wind...so it's toasty!

That the temps in Chicago would be lower than Calgary on average shouldn't be so much of a suprise. My understanding is that Vancouver and Victoria are pretty damn pleasant through the winter owing to some weather magic wrought by currents in the Pacific...leastwise plants that we couldn't keep alive in Chicago because of the winters thrive in B.C. Calgary might get more SNOW than we do...and the ski resort people thank the deity for that, I'm sure...we get those winds off the Plains that are mitigated slightly by Lake Michigan.

Bring it on! Shows just how hardy of a lot we are...kilted in these frigid conditions.
