Thanks for the great post - just goes to show ground work is EVERYTHING. Without it there is no foundation, and a house with no foundation is not stable. Great GREAT story. Hope your friend recovers quickly.
I was taught from a young age that groundwork and building a trusting relationship with my horse was absolutely essential; and every horse I have owned or spent a considerable amount of time training has done anything with little asking.
As far as the 'scarey' part of this story, that is way I wear spurs that have blunt ends (no rowels) and I never put a spur strap on...I've never had anything like that happen, but I have heard of things like this happening, so my personal preference IF I have to use a spur, is no rowel, and no strap...I also witnessed a person at a show get their foot caught in the stirrup, because the spur itself got caught, where otherwise they might have gotten loose. Just goes to show you never know!
I have kept a knife in my pocket ever since we had a truck\trailer accident years ago, and my dad had to ask a bunch of bystanders if they had one, because my QH was stuck underneath my mom's arab, and couldn't get up because the halter held him there (on his side). This was also a testement to my horses trust in me, because when I went to the back of the trailer, they were both trying to move, and all I said was 'whoa, easy' and they both stopped. I climbed in, and slipped a lead around my boy's neck, while my dad cut him free. That horse waited until I asked him, to get up. If a horse could have been frantic beyond obedience that would have been the time, but both those horses trusted me to get them out of their predicament and waited to move until I told them it was okay to.
