This is a neat post and an interesting thing to consider.
Nothing I’ve nominated immediately comes to mind, though i’ve added photos to wayspots that would definitely be considered rare or unique.
Lately it’s a bunch of murals (individually they’re all one of a kind i guess? but not what you meant) and trail markers with a healthy dash of sports fields thrown in.
I guess i’ll have to go with the Taco Bell Wedding Chapel as my rarest nomination:
Then there’s this mysterious sculpture that i could find no info about online. It’s behind a run down apartment complex under some powerlines at the very end of a long dead end road.
I wish i could find out who put it there and why
