When we were kids, as a rare summer treat, my mother would get what passed for a 2 litre bottle of Vess Cream Soda and a half gallon of vanilla ice cream and made ice cream floats.
My dad didn't like root beer, so I wasn't to learn of root beer floats until much later. When I did learn, I accepted the superiority of root beer as a convert accepts his new faith, forsaking all others.
So Mrs. T returned from the grocery yesterday with the old "give this a try. Let me know what you think", says she.
As soon as I come up for air, I'll let her know. In the mean time stock up. Works great as a stand alone, or in floats.
