Chart vs Real World
For those curious, this is a Tethered Aerostat Radar System which is used for US border patrol for low-flying suspicious aircrafts. It is completely unmarked, unlit, and the cable is invisible. We were about 5 miles from the restricted area at 6500. I wouldn't fly much closer to the restricted zone, especially at night, given how easy to miss this thing is. I figured this unique perspective would be fun for people to see!
