That's what happened here. Rather than transitting the traffic
via a "last resort" across town/state, the higher local-pref of a
"local" peer won.
Geography requirements for peers aren't inherently bad. There's
a point where things get extreme, but it would be nice to see
nationals peer in the south as well. If one has peering
requirements, at least set them to reach a positive goal...
