My commute yesterday (sorry, just saw this thread for the first time; I normally hang in C&V) was positively fantastic for early December. Around 45°F in the morning and 55°F in the afternoon.

The highlight was seeing a redtail hawk swoop into a culvert beside the railroad tracks and pluck out a mouse.

So cool!

Just one more reason why I like to ride a bike. Would have missed that if I was in my car or on the train.
