Shot in the saddle????

Posted by Jon Erickson on May 08, 2003

My father used a saying, "shot (or shod?) in the saddle" to mean convinced. Such as; when I came up with an idea that he went along with but with reservations he would say, " Well, ok...but I'm not so shot in the saddle about that!" Has anyone else heard the saying and if so, where does it come from? Did I just not hear him correctly?
