After reading in Gizmondo about the odd structures in the Gobi Desert found by google earth aficionados http://gizmodo.com/5859081/why-is-china-building-these-gigantic-structures-in-the-middle-of-the-desert

Have any fellow OSMers have come across anything like this while browsing aerial imagery during their mapping/tracing ?

Feel free to tell your sketchiest, most suspicious things that you've aerial tracing or mapping !

[Mine: In a economically depressed neighborhood, I found about 15-20 Jaguars (the automobile, not the animal =p] , in all years and conditions, lined up next to each other at the end dead-end street, across the street, a unmarked building, surrounded by a chain-linked fence.
