I just returned from a quick trip to IOA. Storm and Triceratops were closed, but to my amazement the Dragons were Dueling! I don't know if it was a temporary thing due to high demand or what, but they were consistently dueling. Both sides had 2 trains running. The posted times ran between 20-30 minutes, but I have no idea if that's true as I wasn't in the mood to ride. If there truly was a 20 minute wait with 4 trains total running, then it could have very well been just a temporary thing. It was a good thing to see, nonetheless.
