I bet she paid more that that. If its been trained to PSG+ and actually can Do the work and be ridden sensibly by a lower level rider, it will have been worth a hell of a lot more.
I think the one she rode at HOYS used to be registered under the name Northern Blaze (or something like that). I'm pretty sure she was already in the country.....although I could have my facts mixed up!
"unfortunately" one word in that sentence kind of indicates you may have been the seller of said horse, come on spill! i met one of katies horses a while ago at her house / yard and she was gorgeous but not sure how long she has had blaze and whether this was the horse...
