I have recently got back from my 7 day unlimited pass to Universal Studios. I loved majority of the rides at IOA and a few at USF. I must of ridden the Incredible Hulk, The Mummy, and Dueling Dragons at least 5 times a piece. As I was approaching Dueling Dragons I saw what looked to be a old Mine Train coaster kinda like the one we have at Six Flags St. Louis. Does anyone know what this once was or will become? Is it the new Harry Potter ride? It looks like its between the Jurassic Park and the Dueling Dragons sections. Anyone have any idea what I'm seeing? I didn't have my camera with me by then! Thanks. I love IOA!
