Classic knee-jerk paranoia that typifies the current international climate. Apparently the whole blog thing has not been as ubiquitous in the Great White North as it seems to have been down here.

(It was really painful even including a hockey reference in this post at all, I'm so mad at those guys. All of 'em. But that's another post.)
UPDATE: The blogger himself wraps up his experience here. Apparently the title of my post is off because it was US Customs that stopped him -- doubt that the officer would even know who Mats Sundin is. Or apparently how to get his head out of his butt.
