I can prolly help you out if you haven't found someone yet. I'm not a trained riding instructor, but I'm fairly well versed in gaited horses, being an Examiner for the both Rocky Mountain and Kentucky Mountain Horse Associations for many years. (And more than happy to share what i know

)
I'm off every Friday (and weekends), PM me if you'd like for me to come to your place or you can come to mine. I have a (small) arena (well...it's actually a BIG roundpen).
