In the early 1800s, as settlers went west, there were three trails that were primarily used.
The Sante Fe Trail, the Oregon Trail, and the California Trail all converged in Kansas City and went separate ways from there.
The Chisholm Trail was the trail used for most of the cattle drives where the legend of the cowboy was born.
Several railroad lines have also been made into trails and linear parks.
All of these trails have visitor centers, or parks, where rangers could be employed.
