KFC recently built a large Colonel logo near Area 51 which can be seem from Google Earth. Actually, this is not such a bad idea; when the paranoids and UFO watchers check satellite shots of Area 51 they’ll see the KFC ad, and notice they’re hungry. Actually, Area 51 is probably near the top of the list of places people plug into Google Earth, so a lot of people are likely to see this.
