With all the large ranches that started in Wyoming, it's no wonder it is called the cowboy state.
Once word got out that folks were starting ranches in Wyoming, the cowboys flocked to the area. With the herds of cattle and sheep growing larger as the years went on, more and more cowboys were needed for all the chores needed to take care of the animals.
The area became a cowboy culture. There were rodeos, a certain way of talking and dressing, and a cowboy "attitude." This culture is still evident today.
