Denverites like to exclaim, when the stock show's in town and the weather turns cold and snowy, as it did today, that we're having "stock show weather." It's a local belief that the stock show has a magical effect on the weather, bringing cold and snow to Denver with it.
Bunk, of course, and finally a genuwine scientist feller has analyzed the weather data and shown just what bunk it is.
But you just know that no one will listen to him and that every year people will exclaim in wonder at the predictable yet uncanny appearance of stock show weather. In January. Because, if the stock show weren't in town, we'd neeeevvvveeerrr have snow and cold in Denver in January.
