Sorry for getting snarky RT. I'm sure you are right but on contemplating it, I'm sure it was more confidence in myself than her. Its been a couple of years ago that I was in a situation where she refused to go where I asked her. She has gotten much better at stepping down the side of a steep drop into a creek. When she refused it was in the Kiamichi mountains in SE Oklahoma. We were off the marked trails on a VERY rocky river crossing. If we stepped off the rocks we were in black water. I'm sure its one of those times my horse knew better than I did. We found a different crossing and all was good.
She has no problem stepping off of a trailer. Its those 3-4 foot straight drops into water that she likes to balk at but we are working on it. She and I are getting more comfortable with her sliding on her butt down a slope
Again sorry, I was having a bad day yesterday.
