Yep, we had a minor frost the other night, I think, and I'm less than an hour north of Portland. I've been turning the heat on in my car in the morning for the past 2 weeks.
(Though, come to think of it, I can remember being able to ice skate on my pond by Halloween when I was a kid, and these days we're lucky if that's possible by the solstice. Too cold inthe autumn, too warm in the winter, too wet in the spring and too humid in the summer...at least I never run out of things to complain about.
