Happy National Root Beer Float Day!
The ice cream concoction has been around since about 1874 and was probably invented by Frank Wisner, a Colorado soda shop owner.
According to local legend, Wisner was staring out his window one night, looking at the snowy peaks on the dark mountains.
He thought the scene looked like ice cream in dark soda. The next day he combined root beer and vanilla ice cream and from there an American tradition was born.
If you want to raise a glass to celebrate, A&W is offering up FREE root beer floats today, Tuesday, after 2 p.m.
