After several calls to the Mustang Foundation, I finally have approval for a Thursday morning arrival.
J pulled the trailer out Monday and I've been practicing loading and unloading. She is doing it very calmly - at home anyway. I decided to just take her on the stock trailer and have her loose in the front half the same way she came here. I have revamped my goals for this project several times and now I am down to
1- Don't get hurt
2- Don't let horse get hurt.
3- Don't hurt anyone else.
These goals will not get revamped.
