Mls beat beat to it--the last one was closed in Northern Illinois in 2007. That same year my Vet warned me about locking up my pastures to prevent my horses from being stolen and shipped (eventually...in some form) to Europe for human consumption.
Just an FYI--I have combination locks on my pasture gates, and I get some piece of mind knowing that anybody trying to steal a horse WOULD attrack the attention of my neighbors who don't leave for work M-F.
I read about it first in Illinois Equine Newsletter, and also read about N.A.I.S., ANOTHER scheme by the USDA to strangle livestock owners. They want voluntary registration of ALL of your animals--yes, this means registration and tracking of baby chicks as well as your horses. The excuse is that we'll be able to handle an epidemic. The reality is that companies that produce the registration machinery (tags, etc.) will make a bundle from the politicians that they support.
I want our government OUT of my backyard!!!
