Came out last night and... some nibble marks on the lock, and my gloves are gone from the glove compartment. So it was a very thumb-numbing ride in this am @ 2 degrees! But... the lock held, which is the important part. Rot in hell thief.
I stopped carrying the 'massive chain' since it was really obnoxious to use and switched to an Abus 6500. And I found a way to wedge the bike into the corner of the building close enough to the bike rack I can lock it (I can't use those racks, my tires are way to wide).
And to you naysayers on the valve-stem light contraptions... 2 weeks in, they are still working as you can see in the photo!
