OpenStreetMap
As a late entry to the "Top 10" PotW, I mapped using the high res USGS imagery of VA to start mapping Busch Gardens Williamsburg. Mainly I cleaned up the entry roads a little and the main parking lots, but the amusement park tram, a few of the water rides and the roller coasters have been added. Let me know if you're interested in helping to complete the map.

Heh, I was going to comment "Oh no, it looks like someone vandalised over your work" but luckily I read the rest of your entry and saved myself the embarrassment. ;-)

Yeah, orthogonalized roller coasters aren't the best representation of reality.
