Wow - beautiful horses! I'm a huge fan of pintos, but pinto-thoroughbreds makes them better!
However, it does concern me a bit.
Are they really "pure"? How could you get the gene in them without added a paint?
Some of those Thoroughbreds you posted didn't really look like full Thoroughbreds, though. Nothing against you, because it was a site. I'm just kinda pointing it out.
