Not sure, but here is the property information from Lake County GIS: http://gis.lakecountyfl.gov/gisweb/default.aspx?altkey=1594596
Fun stuff!
As a cast member I would wander all around wdw property. I found cool shortcuts, doors that lead to places that I probably shouldn't have gone into...lotsa really cool stuff! Google earth only shows you the stuff on the surface...there is a lot more to be found when you can walk all over.
The Haunted Mansions building houses all the ride controls for MK.
If you use Bing Maps and exit the "preview" (back to the original) and zoom in Bird's Eye on the parking lot area to the right of Spaceship Earth, you can see the Marathon finish line & secure areas from the race. You can also trace the yellow cones backwards through a lot of the property and see parts of the race course.Don't forget about Bing maps. Quite useful, too. Especially when you choose the Bird's Eye view.
I did some research (there's also probably something posted in one of the other forums) regarding the spaces between countries in WS...There are actually spaces in the original design to accommodate 8 additional countries. The reason these have not been developed is that they require a large financial commitment from the tourism board of the country represented. Disney cannot simply add countries without their consent and endorsement. I'm not certain if this is still the case today, but there was a push many years ago to add countries and for financial and political reasons, no suitors could be found.
