Watermelon Cooler (Grown-up's Version)

3 pounds watermelon, cut into pieces

1/2 cup vodka

1/4 cup Triple Sec

3 tablespoons fresh lime juice

thin slices of watermelon for garnish**

In a blender purée the watermelon pieces and strain the purée through a very fine sieve set over a pitcher, discarding the solids. (There should be about 2-1/3 cups juice). Stir in the vodka, the Triple Sec, and the lime juice, pour the cooler into long-stemmed glasses filled with ice cubes, and garnish each drink with a watermelon slice. Add a splash of lemon/lime soda for fizz!

** Forget the thin slice. It may be pretty, but in the south, I use a big ole chunk! The kids want seeds,  so no seedless here... they want to see who can spit the seeds the farthest.
