weeknight cocktail | watermelon lemonade punch

This is the perfect Fourth of July cocktail - and it's ridiculously easy to serve a huge crowd with it.  I've been making it all summer already and my friends adore it.  

Puree watermelon in a blender and mix equal parts lemonade and watermelon puree.  Serve in a giant bucket.  For extra credit, add vodka.  I usually add 1 part watermelon + 1 part lemonade + 1 part vodka!
