Origin of Long Island Iced Tea

We were discussing the impact of Prohibition in my Consumer Behavior class Monday.  One of my students (Clara) mentioned that she had heard Long Island Ice Tea was invented during Prohibition to disguise the fact people were transporting and consuming alcohol. I looked it up online and this may be true. It was one of the two origin stories for the drink.  According to legend it was created by “Old Man Bishop” in Kingsport, Tennessee in the 1920s and later refined by his son, Ransom Bishop.

The drink tasted similar to tea, so that part of the name is obvious.  But why would it have been called a Long Island Iced Tea?  Old Man Bishop lived in a  Kingsport community called Long Island.
