I was just speaking with a colleague doing some work this weekend up at MacDoel in northern California and he reported really low temperatures last night.  Chill is certainly starting to accumulate at the strawberry nurseries, and good thing too since this winter might be a bit warmer than usual.  In other words, it's looking good up there.

Remember that chill can be defined as temperatures below 45 degrees F and above 18 degrees F.
