Hot dogs, cotton candy, funnels cakes and slushes...Visiting a theme park without scarfing down at least one of these foods is like going to the movies without popcorn. Eating junk food at the park is, well, an American tradition. Except that tradition has changed quite a bit since the old days when buying a hot dog and a coke at the county fair would set you back a whole dollar. Now a dollar won’t even buy you a cup to pour the coke into.
