Guess who I saw?

I'm in Ottawa on business and I'm walking back from supper and I did a double take as the leader of the NDP party of Canada (Jack Layton) walks by. I didn't bother him, but it was kinda neat that I saw him walking alone in downtown Ottawa. And that I had this urge to just blurt out "Hi Jack". I don't know if that would have been appropriate, but I'm guessing not too many other political leaders would elicit that kind of reaction (or be walking the streets alone) - and I'm a dyed in the wool Liberal!
