We moved to the current office building around Thanksgiving and until a few weeks ago I have not seen another bike in the bike rack.

We are in an office park, accountants, engineers, etc with very little "customer" traffic, so I just have a very small cable on my commuter bike.

The next bike to show up had a larger cable.

Another bike showed up today that I have not seen before, with an even bigger and just out of the box cable lock.

I wonder if they are consciously buying bigger cables and subcribing to the theory that the bike thief will take the easiest to steal? As my bike hasn't been stolen in 5 months of being parked there every day I'm not worried. But it got me thinking about other places where people commute, do you see escalating lock sizes?
