mysterious helipad location (Dallas, TX)

Anyone want to take a stab at explaining where the Parkland Health
and Hospital System Heliport is? Here's the entry for Parkland's
heliport, TE43.

The location given
http://www.acme.com/mapper/mapper.cg...ht=2&d ot=Yes
is a field (not an airfield, just a field)
http://www.acme.com/mapper/mapper.cg...ht=2&d ot=Yes
51 nm due east of the hospital.

I have a hard time believing that field is the location of two
helipads with one marked "ROOFTOP". Also, the remarks list towers
SE and W of the pads but those are the directions where the towers
are *furthest* from the location given.

And it's continuously attended...yeah, right.

Is it common for helipad locations to be so wrong? Have the
locations of Texan hospital helipads been deliberately scrambled
in the name of "national security"? Conspiracy theorists, unite!
