According to your instructions on how to set the comment field at
<http://www.ew.usna.edu/~bruninga/aprs/n-n-overlays.txt>
the "Wn" in the comment is supposed to reflect the limit.  When Chuck,
KC5AYV, set up all our digis for New n-N he almost certainly used that page
for guidance.  He did that a couple of years ago.

This is the first time I've ever heard that the "Wn" part of the digi
comment is supposed to be the recommendation.

Many local users in Albuquerque still use 3-hop paths.  I don't really think
it is that wise, as our state does have phenomenal coverage for users in the
central part of the state, and enough users in this area that using wide 3-3 
is probably QRMing all over the place.  I try to stick to 2-hop paths where
possible.

I do think that some of the digis are misconfigured --- it appears that they
have WIDE1-1 set as MYALIASes, so a station using WIDE1-1,WIDE2-1 will cause
the same ping-ponging that RELAY,WIDE2-1 used to cause when in an area that
is covered by more than one digi (such as Albuquerque).  I need to drop a
not to Chuck about that.
