They like to say the Insane Inflatable 5K was born on the back of bar napkins, because, well, that’s the truth! Those napkins were the sketch-pad from which dreams came to life one night in an Orlando bar. It’s unclear how inflatables even came up in conversation, but the resulting inflatables are so gigantic you won't believe your own eyes!
