Remind me about Kayson Oler

Flint is a mustang out of Arizona. I got him from the BLM as a 3 yr old in 2017. He is very smart. Mostly ridden him as a trail horse. Needs someone who can ride him often and has some experience. I am selling him because I am going to contstruction school this coming Spring and wont be able to ride him as often as he needs. Very pretty horse, well broke but not for a beginner.
