Is it really that fast/easy? Serious question, because I would imagine it would still take considerable effort and at least a few seconds with anything less than bolt cutters. Next time I'm home, I'm going to try to get at this cable with my cable cutters and see how it goes.

But yes, either way, I'll be using a more substantial lock next time.

As for getting "lucky," that was my first thought as well, but then having your bike targeted for theft isn't that lucky in the first place, so I chalk it up to a matter of perspective.
