However, this begs the question, specifically because we never think about the
existing framework of standards that has evolved around any communication system
(whether that is for physical package delivery, connecting telephone calls, or
We expect that the delivery agent will be able to figure out how to get to a

The refinement can begin with the state, then resolve down to the city, and then

By the time you have resolved down to that level, one is likely to be able to
