Looking at the ones with LONG delays, I notice they are
also in the middle of very high density areas.

N3XKU in the middle of New Jersey, The highest APRS density
on the planet, KD7NM in the middle of seattle, and N6EX-3
in the middle of Los Angeles.  Again, it is not inconceivable 
to me that in the vicinity of these IGates is a digi
somwehre on a high location that either hears too much
or is simply using carrier squelch and it takes forever for
the DCD light to go out so that the packet is finally
transmitted.  Maybe if we looked at the path, we could
learn something.
