Been to the Cody sale. I know a few of the regular sellers. Can be pricy ,depending on the horse and who is bidding on it. The draft crosses are bringing some money. The day before the sale the horses are ridden and roped off of at a arena and you can ride them as well.Fun to attend and drink in the Irma.
I hear the Billings sale is a good one and it can get pricy too. Heard of a grade mare bringing $20,000.
Sounds like you have a nice horse going to a new home.
