Airco Gas Compression Plant
Not to much is known about Airco.  The plant
located in Pedrickton, NJ has been abandoned
for almost 30 years now.  But in its day it
compressed various types of chemical gases.  
The buildings are very much intact.  And if you
climb to the top of the water tower, you can see
for miles.  Over all a pretty interesting place to
visit if that is the kind of thing you are into.
