Hello! I'm supposed to be going to Six Flaggs in San Antonio with my fiance soon, but I've heard mixed responses if I should go on roller coasters or not. I've heard no because some roller coasters are controlled by magnets in the motor and it can mess with my ICD's settings. I've also heard no because of the shoulder harness used on some thrill rides. I'm a pretty small girl, I don't really have any fat or much muscle over my ICD, so I read the harness could do harm. I have also heard everything contrary to what I just said. I just want to know if I can go or if we are wasting our money! I love roller coasters and would love to go, so feedback would be great! Any info for me? THANKS!
