My boss-in-law just announced a geographic research challenge at work: find 10 ultra-obscure items on Streetview and report findings. There are no rewards and no prizes, just an opportunity to outscore the other annotators.
I think you can guess how I feel about this, but here's an Artist's Conception of my current expression just in case.

@zebratron2084 Damn, that sounds like fun too!
And possibly easy if, say, you've been stashing links like that away already.
My favorite things found when doing the maps thing: a solar furnace power plant.
And a series of roads in a countryside that were half-vanished, along with a falling-apart set of stands. With some research I figured out that it was the site of a Grand Prix in the late 80s. :-D
