So upon closer look I think some GL's can be seen in the 85 aerial but hard to say for sure.
The orange-ish cluster blob is in the correct area the Tom Sermento shop should be I believe. Some other white objects possibly patrol cars as well. Wish the 85 view was more clear.
The most puzzling thing is when you jump to 92-94. In that same area 1 very clear orange object can be seen surrounded by 2 white objects (again maybe patrol cars?)
When you compare the size to say the Nothing But Trouble mansion or the Duke farm it's the right size for a car. Why this is so strange is if that is a GL why was 1 car left behind after the Wooten deal in 91? What car would this be? The Forever Young WGL02?
