We had the same temps here today with a -40c windchill. Spring can't get here soon enough for me.
Friends of ours just got back from Arizona last week. They trailered their bikes down and road around for the month of January. Said it wasn't really warm riding, but lots of blue sky, sunshine and NO SNOW!!!
Have a safe trip and enjoy the Arizona sunshine and warmth.
