Thanks for the recon! Too bad one cannot get close, but maybe still worth a visit.
You can get pretty close. There is a combo of barbed wire fence, water tanks, large falling apart crates, huge storage containers, plywood and a bunch of other stuff around the perimeter. Most of the "wall" is pretty tall preventing us from looking over the top but if you stood on your roof you'd probably get a decent view. Not sure how that will go over with anyone on the other side of the wall though. Some areas allowed for easier viewing so a trip around the place to find the sweet spot would be in order.
As for it being worth the visit....sure why not it still fun to explore. Plus there is a geocache there so that's reason enough to go there.
