The fearful stayed home. The actual migrants looked beyond fears of the unknown. Their chief motivation to move west was to find a better economic life than the one they had. Farmers sought larger, cheaper, and more fertile land; merchants and tradesmen sought new customers and new leadership opportunities. Laborers wanted higher paying work and better conditions. As settlers move West, they have to face challenges along the way, such as the lack of wood for housing, bad weather like blizzards and droughts, and fearsome tornadoes. In the treeless prairies homesteaders built sod houses. One of the greatest plagues that hit the homesteaders was the 1874 Locust Plague which devastated the Great Plains. These challenges hardened these settlers in taming the frontier.
