Illinois transplant to CA, casting another vote for "I don't miss the seasons at all." After 5 years in CA, I moved to PA for 1 and immediately regretted it at the first sign of significant weather variation.
After about 10 years out of the Northwest (and a particularly severe drought here in CA), I've finally started to miss the rain a little bit. But I sure don't miss the constantly-ruined plans or the incessant depressing grey.
