The coaster agent is ready to make a report! A week ago I went to Cedar point and rode the Gate Keeper. I was very disappointed...don`t get me wrong ...the design is great ...but the trains have a problem. there is too much play between the cars, which produces a jerking motion when the cars catch up to each other. After the first drop I was ready to get off.The rest of the ride was a neck whipping head slapper. My solution would be to change the coupling to a ball joint configuration to eliminate the loose coupling....The floorless Mantis "poor" It looses momentum half way through the ride." Boring"
