Hey Disney . . . . this seems like a no brainer to me . . . the driver of the dragon should have a shut off valve for the propane, and perhaps a control for an on board fire suppression system in case of a fire in the head / neck area where it is difficult for CM's on the ground to reach. Since you are going to have to make repairs to the float, now would be a fantastic time to make these additions. I bet, had these been implemented from the beginning, the repair time for this would have been minimal.
