Finally compared my photos of Chicago from two different shorelines and it clicked

I took a zoomed in shot of the skyline from the Indiana Dunes last Saturday (about 30 miles away) and then drove 15 miles north to New Buffalo, Michigan for the same view. The buildings were visibly lower behind the water at the farther spot, with the lower 200 feet or so of the Sears Tower just gone. Has anyone else tried a simple two-location test like this to show the curve in a straight forward way?

Heard a guy on a podcast talk about how this exact test is the easiest way to prove the curve without a bunch of math... just line up your camera and see what disappears. Pretty wild how consistent it is once you actually step away from the shore a bit.

Did you check the weather conditions before you went out? That can mess with the visibility and make the curve look more or less obvious. I've done a similar test with a lighthouse and a boat, and it really drives the point home when you see the bottom half just disappear.
