The Can/U.S. governments shut down the Peace Arch border crossing once a year for us. We have a big event called Hands Across the Border where Scouts from Canada and the U.S. meet up and trade badges and whatnot, followed by a parade and a ceremony. Last year there was a Coast Guard Hovercraft out in the bay to give us a demonstration, but as it started moving a looooong freight train went by and we missed the hovercraft. LOL at 10,000 people watching a freight train.
The level of invisible security at Hands Across the Border is pretty amazing. You KNOW the powers that be are watching you, but you can't see them. Two years ago, a leader (not me!) accidently blew up a propane bottle and there was a fire truck and 2 police cars there within seconds.
