Did you know that, at least according to a survey conducted by nationaltoday.com, 67 percent of Americans prefer frozen margaritas to on the rocks? And that 65 percent want their rims nice and salty? This matters, because Thursday, Feb. 22 is National Margarita Day, which is our chance to get tipsy off of honor the sweet-tart tequila beverage. Whether you like slushies, salt or sugar, we can all agree that we like margaritas best when they’re cheap.
