I am very familiar with Crimson King. It is no longer being run as that though, it was split and leased by a couple of different people that boarded horses.
What are you wanting to know about it?
If you are looking to board in that area, I would recommend Antebellum Farm, which is right next door.
Crimson King Farm was a famous Thoroughbred ranch of a few thousand acres at the turn of the last century. The heir lost the place eventually, being interested in cock fighting over horses! Sad to see the old glory gone. But...
It is split up and has several boarding facilities on site now. I am very familiar with one... Shyla Farm which is well run, clean and an honest establishment. I would recommend it to anyone needing temporary or permanent stabling. She has a separate stallion or brood-mare barn.
Its only 2 miles from the Horse Park... I have stayed there... nice people.
