In celebration of yesterday being the first day of summer, we thought about summery, sunshiny drinks. Thoughts of Tequila Sunrises came to mine, as well as the good ol' beer/vodka/lemonade Summer Brew. But today, for your summer slurping pleasure, we bring you, courtesy of the The Quarry Golf Club of San Antonio the Summer Fling Margarita. It uses Skinny Girl Ready-to-Serve Margaritas mixed with Fresca, plus a little more tequila if you want it stronger. So get your solstice on tonight (as if we ever needed an excuse).
