Hi Terry,

You may want to peruse this IRTF RRG discussion on this topic:
http://www.ops.ietf.org/lists/rrg/2008/msg01781.html .

The short short version is: geographic route aggregation has been
demonstrated impractical because aggregation depends on administrative
vectors (e.g. which ISP you pay and which ones they pay) as well
physical and technological factors. For the long version with the
step-by-step gory details, read the the RRG thread.
