Locoweed

Here is something I had never heard of before.  Apparently there is a weed that, if eaten, will make horses and other farm-y animals go crazy if they eat it.   This woman takes the time to go around her 40 acres and clear it out.  She had a fantastic blog, by the way.  Her menagerie is mesmerizing.
