Well, friends, I am SO happy to tell you that Boomer has found the perfect home!
I am so glad that this story has a happy ending!
I posted Boomer on endurance.net classifieds and got several replies. The one that stood out was from a couple from Iowa. They have several decades of arabian and endurance experience. They have thousands of competition miles. They do FEI rides. They travel to Florida in the winter and do rides year round.
They came to meet Boomer and were very happy with him. They are aware of his behavior issues and did not seem phased by that at all.
This is the perfect situation for Boomer and I am able to move on with a happy heart!
Thank you all for being so understanding and supportive during this difficult time for me!
Horses will always be important to me. I hope to take frequent riding lessons and continue to learn and improve. I also hope someday to own another horse. But, for now, I am endlessly happy to spend my days with this little joy:
