Rendezvous Balloon Rally Riverton, WY July 2011 "Jack N D Box" was the only character balloon at the rally this year and was piloted by John Harlow from Springfield, MO. The crowd was patient as Jack's arms, hair, nose, and even the toys, surrounding him were inflated. The local paper reported that Jack required a team of 10 people and as well as four times as many tanks of propane to fully inflate. Jack is a HUGE balloon, stretching 110 feet, twice as long as a regular balloon. He looked like Gulliver reclining on the field. Slowly, Jack began to rise. . . and rise. . . and rise. . . until he was fully upright. Jack was impressive on the field; however, I can only imagine how he looked aloft since Jack remained on the ground the day I attended.
