Will link to a street map for these TA street pics.
This is blocks away from TA's house, on the eastern side of his development, which
is also the eastern-most edge and border of developed Mesa. To the right is just desert.
The sign is for Mesquite, the road into TA's development.
The space shown here is large enough to park a tractor trailer, and this border road doesn't seem to be heavily trafficked.
Do you recall just how close that spot is to the little pond along that road? It seems very close to have dumped anything there but who knows with her...
