My family and I rode back in September at a MNSSHP. Pirates had been down for most of the evening and had just reopened when we jumped on. We were the first boat to load. While still sitting in the load, all of work lights came on. The CM manning the controls took a phone call and begin to announce that everyone should evacuate the building immediately. I thought that they would unload the boat, until another CM yelled to the guy at the controls to "Green Light" the boat. We were a little apprehensive since they had just announce for everyone to immediately leave the building, but sent our boat through.
There was no audio or music on the ride, but all of the AA were working/moving and the overhead lights were on. It was quite a neat experience. When we finally made it to unload, the poor CM apologized and said it had gone down multiple times that day. We'll miss it when we are there this June, but I hope Pirates gets the refurb it deserves. It's definitely a favorite of our family.
