To make this refreshing drink, you first fill a collins glass 3/4 with ice cubes. Then, add 2 shots of any tequila of choice. Add a splash of lime juice. Then, fill the rest of the glass with your favorite grapefruit juice (I use ruby red grapefruit juice cocktail). Stir, and enjoy! A great drink for any time, but especially good on a hot summer day/ evening.
