Star Sighting

You know the stories about how people see actors everywhere in LA?

We were walking along Santa Monica beach early one morning, and this guy looks really familiar. As the walked by (about a foot away) I realized who he was (though I had the wrong name). John was walking really fast, followed by a boy (maybe his son?).

I know there are websites where people call in and track the location of famous people every moment. Not sure I understand why you'd want to do that, but it's fun to have someone you recognize from the movies stroll by. Such an LA experience!
