Oooh I forgot about this one.
The last time I went to an amusement park was years ago at Carowinds (NC/SC). I was riding Drop Zone (tall, chairs go up, lock, and then drop you). The line is always long for this ride. We finally made it, I sat down with my friends and pulled the lock bar over my head and shoulders. The attendant comes around and locks the buckle between your legs to the lock bar. They couldn't get it to click. I had to walk off the ride and through the exit, alone, because I was too fat to ride. I never went back.
I sometimes wonder if my love for roller coasters has waned since I haven't been on one in so long. I hope not. The thrill was exhilarating! Can't wait to try again.
