In bringing back this long-missing contest, I'm doing a couple things differently. However, I'm not going to say what they are just yet.
Where in the QC is this?
Guess #1 at 9:00AM was the correct one. Here's a wider angle:
Rather than combine cabs, as someone else guessed, I believe these are rows of hundreds of Compact Excavators like this one. In the wider angle you can also see a couple dozen road graders, and generally millions of dollars in equipment.
This location is actually outside of the area that I defined for my Where in the QC is this? series, and obviously it is an overhead shot, but the correct answer was still guessed in less than 2 hours. Impressive.
