I brought my lock up to my office from the rack where I leave it. I'm not going to be using it for a while so why leave it out in the elements.
On my subway commute I saw just one rider crossing the Manhattan Bridge this evening and 2 this morning. Usually there are lots, even on cooler days. But with the temp below 32 the riders really drop off.
On another note, on the block where I lock my bike one of the messengers that hang out there had his bike stolen. Or at least he thinks he did. I didn't get the whole story, just what I heard him say on his phone.
