Simi is a 16 yr old quarter horse mare. I have had her for her entire life and it’s with great difficulty that I part with and I wouldn’t be if life hadn’t gotten in the way but she is an awesome trail horse. Is good with most horses but does have a dominant personality so care has to be given in pasture situation. I have had anyone from small kids to adults who have never ridden but she is performance bred so she is very quick so I wouldn’t put a total beginner on her but a confident kid or adult would do great with her
