All this on-ride flash photography talk reminds me of the time I was on Dinosaur sitting behind an older aged couple from Cuba (I could tell from their accent). The woman, God bless her, had her little camera out with flash trying to take pictures at every turn. Imagine a raggedy Ann doll being thrown across the row left and right for the duration of the ride. She took plenty of photos. She got photos of the ceiling, the back of other passengers heads, her feet etc. Just flash going off every few seconds in no particular direction. It was pretty funny. They were all smiles when the ride was over so at least they had a good time.
