If I were to get nastalgic about IOA, it would be seeing guest drawn to head left by the (natural) roar of the Hulk. I feel the reverb killed that.
Being so close to HP, I’m not sure a JP coaster could do something like that, but I think it would be way on theme if they found a way to have some sort of Dino roar coming from the woods while a coaster flys by.
