A scoop of vanilla ice cream in an ice-cold mug of root beer is a cool customer on a hot August day. That’s especially so Tuesday, Aug. 6. It’s National Root Beer Float Day.

Some accounts credit Frank J. Wisner of Cripple Creek, Colorado, for coming up with the root beer float, also known as a Black Cow, in August of 1893.

It seems Wisner, owner of Cripple Creek Cow Mountain Gold Mining Co., was thinking about a line of soda waters he produced for the folks around Cripple Creek when he saw a full moon shining on a snow-capped mountain, and it reminded him of a scoop of ice cream.

As the story goes, Wisner added a scoop of ice cream into a mug of his childrens’ favorite soda, Myers Avenue Red Root Beer, and the root beer float was born.

Accurate or not, it’s a good story. We came up with some of our favorite root beer floats, or root beers screaming for a scoop of vanilla ice cream.
