Here's why:
* Constant Movement: Cowboys would drive their herds for long distances, making it impractical to have a house at every stop.
* Limited Resources: Houses were scarce in the wild west, especially during the time when cowboys were most active.
* Practicality: Sleeping outdoors was a practical choice, allowing cowboys to be close to their horses and to spot any potential danger.
They would use bedrolls to sleep on the ground. These were typically made of a blanket or a tarp, sometimes filled with straw or grass for padding. Cowboys also used chuck wagons which were mobile kitchens, providing them with food and a place to prepare their meals.
While cowboys might have slept in houses during rare occasions, like visiting a town or staying at a ranch, their primary sleeping arrangement was under the open sky.
