I used to be in the Air Force tracking things in space, and atmosphere. So, that stuff is still dear to my heart. I found this website while I was surfing NASA website. You can see the shuttle and or international space shuttle, either separately or together when they are docked, with the naked eye. They also have a world map, which shows where it is currently. It goes around the world so fast. It looks like a big, white light, flying VERY FAST through the sky. Everytime, I see it, I just think it is so cool. Awesome.
If there are any other space geeks out there like me, here is the website http://spaceflight.nasa.gov/home/index.html
Once you are there, click the tab "Realtime Data", then click "Orbital tracking". Then it takes you to a different screen for "Sighting Opportunities". Then, click on your country, and city. I just thought I would post this for FYI.
