[pct-l] Poultry sheds at Mile 4.6?

[Ron Graybill]

At about Mile 4.6, if one looks south across the nearby railroad tracks,
one can see a large collection of long sheds, 15 to be exact (best seen on
Google Earth).  Does anyone know what sort of an operation goes on there?
 I'm guessing they are sheds housing thousands of chickens, but who knows?
 Before I started my section hike, I wondered if one could simply get off
the trail, cross the tracks, and get some water there.  But wow! that would
be an ordeal, as the terrain is very steep and rough between the trail and
this poultry farm (if indeed that's what it is).
