Today is national Margarita Day.

There are 3 or 4 versions of where the drink was invented. I like this one the best because back in the 60's and 70's I spent a good deal of time there.

From Wikipedia:

"Hussong's
Hussong's Cantina is the oldest and best known cantina in Baja California, Mexico.[1]

The original Hussong's is located in Ensenada, Baja California, Mexico, and was established in 1892.[2] The second Hussong's Cantina opened in Las Vegas, Nevada, in January 2010.

Hussong's is reputedly the place where the Margarita was created in October, 1941 by bartender Don Carlos Orozco.[3] He concocted a mixture of equal parts tequila, damiana (Cointreau is used now) and lime, served over ice in a salt-rimmed glass for Margarita Henkel, daughter of the German Ambassador to Mexico.[3]"
