For some reason this update from UPS fascinates me.

I don't really think about optimizing our ground transportation network but it's pretty interesting. This short snippet really got me thinking about what must be going on at UPS. They must have a bunch of guys on supercomputers back there trying to optimize routes. It's also interesting how UPS thinks of their traffic. They seem to call each major city pair that they service a Lane, much like a shipping lane. I would really love to get my hands on some of their maps!
