Watching the spacestation go by is pretty cool... I saw it a couple months ago with one of the shuttles right after it undocked. It looked like two bright stars moving across the sky real close to eachother.
I used to see them all the time when I lived in Kitty Hawk, right off the bypass across from medical center. I had a crows nest on top of my place and could see for miles with almost no light pollution. It is amazing the things you see when there isn't something that interferes with your line of sight.
