Any knowlegable horseperson will tell you they are three things..
Big
Dirty
Dangerous..
Our romantic notions and the fact that horses are not part of our day to day life, as they once were, has divorced us from some of the reality of dealing with them.
The more you know, the more you know what happens, before what happens, happens...
This happened fairly close to us in the wilderness area. The radio reporter said that the husband TRIED to do a tracheotomy on the wife without success. It was a 6 mile ride out to get any help at all. I have been back in there and there is no cell service or services at all. You are pretty much on your own.
The woman was an experienced back country rider and they were from Tennessee.
