What were the main places did the cowboys move to during the western expansion?

During the western expansion, cowboys primarily moved to areas in the American West, including Texas, Wyoming, Montana, and Colorado. They often followed cattle drives along trails like the Chisholm Trail and the Goodnight-Loving Trail, leading to railheads where cattle could be shipped to markets in the East. Additionally, cowboys settled in frontier towns that sprang up along these routes, contributing to the development of the cattle ranching industry.
