If you only have time for one small-town festival this summer and you want it to be filled with enough silliness to make you forget all the serious stuff going on in your life, consider the Annual "Cheeseburger in Caseville"  Festival. It is too big for a weekend and runs every year in August. As you reach the city limits, you’ll be greeted by more pink flamingos than flock anywhere else north of Miami as the small beach town of Caseville morphs into Key North.
