The Four Sixes ranch in Guthrie, Texas, is one on my favorite places.  I was lucky to be able to attend the Return of the Remuda horse auction in early October.  Although it was cold and windy, the auction itself was very engaging.  On average, it took about 2 minutes per horse and there were 166 horses in the catelog (not all showed however).  $700 - $43,000.  I was encouraged because the older, seasoned horses were very popular, brought a good price, and are still in high demand.
