What one sees almost as soon as they drive into a major Utah town, especially Salt Lake City. It consists of a bunch of Mormon mothers and irritated drivers from out of state swapping lanes with no turn signal or warning. This causes immense traffic jams, that clear up two times a day for ten minutes. Should one happen to be behind a Mormon about to contribute to the Mormon shuffle, it is customary to try not to flip them off, even though 50% of the time they will flip you off for being behind them. The only way to escape the Mormon shuffle is to not drive in Salt Lake City or other major Utah cities.
Oh man, we're going to have to brave the Mormon shuffle to get to Macy's today kids. Better bring some extra movies.
