Google Earth + Panoranimo: Quarry in Thornton, IL w/ I-80 Crossing
What was that?
Sometimes you'll be on a car trip, like I was, and do a double-take, as I did. I was going over this bridge somewhere in Illinois, my GPS taking me to O'Hare.
Suddenly, on both sides, steep cliffs, a drop off. Clearly a quarry of some kind.
I wished I had a better view and quickly scanned for exits and a better viewpoint.
In retrospect, I could have found one, but Google Earth, linked with Panoramino, is the next best thing.
