LOL - for many years, the PA announcer at Michigan Stadium for the football games was Carl Grapentine. At the of every game he would announce the change in the traffic pattern on Main street down to I-94 as follows: "Traffic Southbound on Ann-Arbor Saline road will be one-way following the game". No kidding Carl? Cracked me up every time. At some point he must have started doing it on purpose because it had become tradition I think.
