Fun: Google Tourism
Recently, Google Maps added world-wide satellite imagery. I've been taking shameless advantage to visit a bunch of places that I think might be interesting to look at from the air. After she saw what I was doing, my wife pitched in to help. Here are the fruits of our sojourns.
The Great Pyramids (don't forget to visit the Great Sphinx too.)
The Arc de Triomphe
The Grand Canyon
Epcot at DisneyWorld
Statue of Liberty
Golden Gate Bridge
St. Louis Arch
Mt. Saint Helens
Bristol Renaissance Faire
Cape Canaveral (Shuttle Launch Pad?)
Maybe at some point in the future these will be worth visiting, but right now you can't get in close enough to matter for one reason or another.
Sydney Opera House (inadquate photography)
Stonehenge (inadquate photography)
Capitol Building (deliberately fuzzed, sound dumb?).
Mount Rushmore (bad angle)
Taj Mahal (inadequate photography)
Great Wall of China (I can't find a section that's been adquately photographed.)
Obviously all of this stuff wasn't photographed yesterday, and here's a few locations that show the time lag.
Twin Towers Site (before new construction)
Cape Girardeau's Mississippi Bridge (The new bridge is now finished, the old one gone.)
