Interesting. that's about what it was here in DC earlier this morning (~3 or 4C). Riding in knickers and a lightweight Ibex top under my jacket I swear it felt just as comfortable as on a sunny summer day in shorts. Very sweet. I did a sherpa run in to the office to stock up my locker and larder.
Not sure if I'm so quick to celebrate global warming, but I'll sure as heck take a nice, sunny, late-autumn day after the overcast, chilly oppressive crap we've had around here lately. (and yeah, I know you were just joking

)
