This is the perfect drink for your upcoming 4th of July festivities!  It's so easy, requires no prep work, and nothing tastes more like summer than watermelon!  All you need is a watermelon (definitely go with seedless), mint, lime, club soda and rum.  Take about a cup of watermelon, muddle with a couple leaves of mint, and a wedge of lime in a shaker.  Shake with some ice, pour into a glass, and add about a shot (or two) of rum and club soda to taste.  If you're making a big batch of this I would say go ahead and blend up the watermelon to make it even easier for yourself.  

Hope you all have a safe and fun 4th of July weekend!
