Yeah very traumatic. I hate thinking about it and it just happened a put a month and a half ago. I just got out of crutches and my cast. The float was actually a supersized trailer made to fit tractors and building machinery on it and that night it had 45 football players on top of it, plus it's original weight. It has two wheels and when my right ankle got rolled underneath, I managed to crawl sideways ignoring all the pain in my knee at the time. When it got done running over my knee and ankle area, I tried to get loose and my friend tries yanking me out but my ankle was wedged in between the two tires... Then began round 2 of the incident. By this time everyone had jumped off the trailer and was yelling "Stop" or "Go backwards" or forward. Well the driver stopped, as this 1 ton trailer was parked complacently on top of my ankle. Then he backed off of it, stopped, then accelerated and RAN my foot over again... I blacked out after that and then I came too when I was being put into the ambulance. I ended up with a major MCL sprain and the 2 broken leg bones. I'm surprised I didn't shatter my ankle and so is everyone else who has heard this story. I'm also surprised I got myself in a cocked position adjacent to the trailer before it absolutely destroyed my knee and my hips and my ribs ect; That's the story.
