The problem is the educators are also misinformed!  The "fixed" path is -STILL- 
not right.   The station is now using a three-hop path  (WIDE1-1,WIDE2-2) in a 
congested urban area rimmed with numerous digipeaters on 5,000-foot mountain 
tops.     Each transmission is now creating 4-6 retransmissions IN THE SAME AREA.

Normally, one should be using a two-hop path  WIDE1-1,WIDE2-1 .

However, because of the unique terrain of SoCal  (A coast and basin with a 
population of around 20 million surrounded by multiple 
4,000-to-7,000-foot-high  mountain ranges), the recommended path in the greater 
SoCal area has been for many years
   WIDE2-2    only.

WIDE1-1 home fill-ins are heavily discouraged here since stations on the ground 
in the greater L.A. basin and adjacent coastal areas can easily hit the high 
mountain-top "superwides"  tops directly.  (Home fill-in transmissions just add 
to the congestion and are totally unneeded.)  In turn, the mountain-top digis 
here treat WIDE2-2 as a single hop.     Even so, one typically hears 
re-transmissions from several different mountaintops simultaneously around here.
