At the moment I'm on a little coaster tour in Italy and I wanted to do POV's with my GoPro and chest mount on the coasters. At Gardaland I could do them, but only on the small kiddie coaster and the water rides. I also tried it on Magic Mountain, but they said no! But just an hour before, a girl asked the operator where she should put her phone to ride the coaster and he replied, that she should put it in her pocket of the trousers, where most phones which get lost come from!!! So a phone in an open pocket is allowed but a chest mounted GoPro not!?!? What is wrong there?!
I'll try it tomorrow at the two B&M's. Please wish me luck!
