When you hail from a cold climate like me, spring is something you earn. I suspect year round warm weather is either for the weak or people with good karma.

And the forests where they live have been hammered by bark beetles. The new research on how warmer spring weather speeds up the life cycle of the bugs is fascinating and telling: http://summitcountyvoice.com/2012/03/16/global-warming-pine-beetles-thriving-at-higher-elevations/
