To ride on a mule compared to a horse is like riding in a Cadillac compared to a VW. This is what a guide told me riding into the Bob Marshall Wildress Area.
They are smooth.

If anyone has ever taken this one fly fishing trip there, I forget the name of the streams, but you go over a trail where your leg is overhanging a straight down drop of approx. 500 feet. You also cross over the Continental Divide, where the snow was still 10' deep in spots and this was August.
