One of the buyers that was out last week was telling me that HYPP N/N horses are dying from heat. I don't know that I believe this, she saw it was in a study in one of the horse magazines but I've not found it anywhere.
I know it wasn't Sock Broker and I don't think it was Mr. Yella Fella and that leaves Tee Totally Cool. Cool is the prettiest one he has (imho) so I'm hoping he has another stud down there that I don't know about.
Nothing surprises me about Impressive horses, I have one myself, but in this case I don't think it was the heat, it hasn't gotten above 85 here yet.
