I loved rollercoasters as a child!
They seem like a lot of fun, I'm not really a fan of amusement rides though, especially elevated ones on a track, I have a fear of heights!
I'm scared of heights when it comes to buildings. Have you been to sixflags?
I haven't, I've only been to an amusement park once I think, I know they feature various attractions besides the rides, so I focused mostly on those other things due to the heights fear.
