I visit traveling fair most weeks Very Happy i have never seen a Waltzer with locking bars.
Yup as i said earlier in the post. There is simply no need for locking bars because of the force involved keeps you in the car.
As for the rider's not being safe, u will find that they are checked daily the same as Theme Park's
Precisely. Although I wouldn't say as much as Theme Parks. however yes they are tested daily and if there is a problem, they simply will not open it. - if you see a ride open up without testing, doesn't mean its not been tested earlier in the day.
You have to bolt the passengers down so there is no chance of stupidity.
Not really, if the rules are clearly set out (which i have seen signs on nearly all rides telling you what you can and cant do) and you ride at your own risk. as long as the ride can operate without bars, i see no reason why it shouldn't. A good example is a round up ride. (or meteorite as you may know it as) If people behave on these they are perfectly safe, i tend to push the limits a bit but not to the point where i'm unsafe on it. If however they put bars on this type of ride, it would ruin it and there would be no point in that kind of ride existing. Its all about trusting the guests not to do something stupid, and if they do, its there own fault for not having common sense and also reading the signs.
