Yep. 6 yr old is about when you start serious training on one. I won't ride mine til they are 3, and I start them in a bosal. At 4, I go to a snaffle, and they are 5 before they go to a curb. Old school ropers will tell you a horse doesn't have his mind right to carry you to NFR til he is 10. I watched that ranch horse sale. The $12,000 average was due to the 3 and 4 year old prospects they sold for 4 figures Older, finished horses with earnings, brought 2 and 3 times that $12k. A few sold in the $50k to $60k range.
