Sorry to hear about the achilles--that definitely bites.

Here it's cold this morning: 13 F with a 10-15 mph wind (riding into it, of course). Not really any colder than quite a few other mornings this winter, but after a week or so of exceptionally mild temps the sudden plunge back into seasonable weather was a bit of an adjustment. More in my head than anything really, I guess. Once I got going it was business as usual.
