This made me giggle when I seen this post. I went zip lining back in October in Mexico. I got stuck in the middle of the zip line I had no arm or stomach muscles to pull myself back I was crying and screaming "I'm gonna die." lol I laughed about ur now, but it was really scary when your heavy and have no control. Lucky the people working there helped me. My boyfriend felt horrible because they had to grab him before they could get to me. He said it was a horrible feeling sitting there watching me cry and there was nothing he could do for me. Needless to say I probably will never do zip lining again. Apparently the zip lining place we went to was featured on Fear Factor and I can tell you I see why. We were going like 60 mph on the one I got stuck on all because I put the brakes on too early because of fear. It's a funny story but I can actually say I did it.
