For a couple of weeks we've been looking very intensely at the number plates of cars. We’re playing a game: we'd like to see at least one car of each canton. As Switzerland is quite small we made the game a bit more difficult, we don't count trucks, only cars and only if we're in our car and if the other car is driving (not parked). There are only four cantons left, all the other ones we already have on our list. This is also a good exercise of Swiss geography.
