I would notice a Google Maps Icon anywhere I went, but I would only expect to see it on a computer screen. If I saw one in real life I'd consider myself in need of a nap, and/or drugged by an enemy or prankster.
"I'm in the twilight zone," I'd think. "Somehow I am passing through someone's desktop view of Google Maps. Just ignore it, and keep going." (That would make a cool YouTube video.)
This photo is real. The icon is actually a wood & cloth structure and would have made a dope April Fools day prank. Google should have put up a bunch of these along with Gmail Paper and Google TiSP.
