"I received an E-mail this morning from Dave [AB7E], who explains his
location as being just two miles from the Mexican border, south of Sierra
Vista.  That puts him about 112 miles farther than I am and about 10
miles  farther than [W9]NGA in Green Valley."

Pete, KJ7WY (who also worked 3B9C on 160m) e-mailed me that he has a list
of 13 southwestern USA stations that have QSOed 3B9C on 160m.  He
provided the coordinates of AB7E as 31.4N, 110.2W.  That makes AB7E the
farthest (via short path) from 3B9C:

W9NGA = 18553.086 km (11528.353 mi) at grid subsquare DM41lt (the center
of which is at 31.8125N, 111.041667W) at a 23.13 degree bearing.

AB7E = 18563.010 km (11534.519 mi) at a 26.95 degree bearing.

It's interesting to note the relatively large difference in beam headings
to 3B9C for two stations in Arizona that are less than 56 miles from each
other.  This is typical for near-antipodal distances.
