We're not sure if this one counts yet; my teen thought this one had to be by design! We had found several Hidden Mickeys elsewhere in the parks. I think we got a little crazy on the hunt!
Thanks! We enjoy HM's so much!
In DinoLand, U.S.A. at the photo posing spot at the rear of the Fossil Fun Games area, look in the smoke or clouds of the drawings on the poster boards; a three-circle image is on the front poster behind and below the rear red fin of the car.
