My grandfather and my father had wheat ranches, so we had quite a few trucks around and a lot of mules. Talk about horsepower - we had mule power.

Some kinds of animals burrow in the ground; others do not. Some animals are nocturnal, as the owl and the bat; others use the hours of daylight. There are tame animals and wild animals. Man and the mule are always tame; the leopard and the wolf are invariably wild, and others, as the elephant, are easily tamed.

In 1964, when Lee Iacocca said, 'Shelby, I want you to make a sports car out of the Mustang,' the first thing I said was, 'Lee, you can't make a race horse out of a mule. I don't want to do it.' He said, 'I didn't ask you to make it; you work for me.'

I spend most of hunting season at the ranch. We all love to hunt whitetails, and we have a pretty good supply in South Texas. I also love to hunt elk in Arizona, mule deer in Utah, and I've been to Canada to hunt caribou.
