Last meadowhawk?

I have counted out the Autumn Meadowhawks before, but each time I've declared that the adult odonate season is really, truly over, the tough little critters have proven me wrong. After two rounds of killing frosts last week, I was pretty certain that Sympetrum vicinum, which I don't believe has any inherent anti-freezing mechanisms, save finding an above-32-degrees microclimate, had left us for good. On Saturday the 9th, and today, an almost Indian Summer day, the meadowhawks thumbed their red noses in my face. The skimmer-type dragonflies put in a strong showing, with perhaps as many as a dozen on the wing, and while they were a little bit on the skittish side, I was often able to get close enough, with my 55–200 mm telephoto zoom, to get a good shot. There's serious cold in the forecast, with temperatures perhaps dropping to the low 20s, so today might be the end of the line for the insects. But I'm not counting out the meadowhawks just yet. Once the chill passes, perhaps these odes will put in another appearance—and continue to delight and amaze this observer.
