Anyone know anything about it?

I know that they're selling off their assets so that they can focus primarily on media and promoting western sports. 

They are selling both the ranches.  And Western Livestock is doing a "complete" dispersal of the horses they have.  

I think that Sheridan got tired of having all of the "stuff" surrounding the horses.  He is still riding, but as you know it is a lot easier to show up at the barn, and show then supervise the barn.  

I don't think Sheridan is that invovled with Teton Ridge's ranches, he's got his own even bigger ranch. I do think Teton Ridge thought their program would be bigger than it ended up being so they're cutting their losses & just moving on from a bad business investment
