Does anyone know what's going on with Volcano? It was closed the days I went last week as well.
Last I was there, one of my park ambassador friends told be it had been shut down for the week before (I went on the 17th). He said they were having problems launching fast enough. He said it could only launch around 40mph and kept rolling back...
Considering the magnets have their own AC unit, I think it would be the heat. Maybe the magnets are overheating and the ride deliberately lowers the power put into them.
