The gentleman who owned the pony camp I went to was M De Pas. He raised racing ponies and had around 400 head back in the early 70's. I'm sure he's passed away but he did have 7 children who might of continued the ponies. He was also well known for his peaches.
Have you made it out to Haras Du Pin? Every September they have the National Percheron show on the grounds. Once every 10 years they host the World Percheron Congress. I was going to the 2001 Congress but my plans were put on hold because of September 11. I already planning for 2021.
