I know there were a couple times in the 1970's when schools in the Nashville area got caught with wrong decisions. A few times, kids spent nights on buses instead of at home; since then they typically call school when snow is even mentioned. The most recent time, I believe, was in 2003 when the NWS was calling for a few snow showers and we got several inches. The problem was that there had been no pretreatment, everyone was at school/work; then when it started snowing, when it became obvious the forecast had failed, everyone hit the road at the same time, only to have mass gridlock, kids spending the night at schools, it was a mess.
