On July 3rd, while out watching some fireworks by Hidden Valley I caught the International Space Station passing through just after dusk. It wasn't that impressive to watch -just a little dot moving slowly across the sky- but it made a nice photo.  The fainter streak in the upper right-hand corner is from the blinking light of a passing airplane.

You can check shuttle and space station fly over times for the United States here.            30 sec./f5/iso640
