Have you ever had a close call?

This last Thursday, a stable hand tied my horse to a fence because they were doing repairs and wanted him out of the way. Why they didn't put him in another stall or at gr, I don't know. Well, they tied the lead way to long and did the improper release not. We he had circled and move around so that it had wrapped around his right back leg a couple of times. Well, when Shadow is bored when tied, he likes to put one of his legs in between the fence. Not a smart idea but he gets out on his own. He know better not to when someone is around. Well while tied, he got his leg between the fence and when he tried to get his leg out, he couldn't back up because of his leg being tied up and fell under the fence and began to thrash around, one of the boards,the one his front leg was propped on, broke and one of the broken pieces was poised and ready to stab him in the barrel. Some people got to him in time and tore the fence apart and got him out. They couldn't release the lead because the not was incorrect. His back leg that was trapped by the lead is cut up but other then that, he did not break a leg or get stabbed. I was actually on my way to the stable for work while this all happened and it was not so great to see my boy like that and having the stable hand, who was a teenage boy, balling his eyes out and saying he was sorry. I didn't charge the kid anything because it was an accident and I am just greatful that Shadow is alrite and will be fuly healed in a couple of weeks. So everyone, my question is, what is a close call that has happened to your horse? A bad colic? Caught in fence? Bad fall? WHat?
