Ignoring digis in the ALOHA calculation is sorta meaningless, since it's the
digis that help saturate the channel.  Does UI-ALOHA take that into account?

Nevada, Utah, Colorado, Texas, Arizona, Kansas and Oklahoma.  There are a fair
number in New Mexico, of course, but they're in the minority.  A mobile station 
in Kansas got its posits to my station via a 3-hop digi path, a distance of 
487 miles.
