Camping along the trail was not recreation but a way of life for immigrants traveling from their old homes to new ones in the West, and for freighters and drovers moving goods. Immigrant trains and freight trains usually had about twenty-five wagons, enough men for protection but few enough animals to find sufficient grass. At night the wagons were arranged in a hollow circle or square to form a protective wall around the little city inside. Men cared for the animals while women cooked on stoves or over open fires. Meals were simple because only the most important foods were carried on the journey, with bread, bacon, and beans most common, while biscuits and pancakes were popular because they were easy to prepare. Finding berries or buying special foods at stores such as Hollenberg's was a treat. Women washed dishes or clothes, men repaired harness and did other chores, and children gathered firewood or looked for berries. After the work was finished, children played and adults made music, told stories, talked about business affairs, or rested for the next day's journey. If there was room, entire families slept in their covered wagons, but often men and older boys slept outside on the ground. The wagon carried goods and sometimes people, though usually only the very young, the very old, and the sick rode while most adults and children walked to save the strength of the draft animals. Cooking utensils were basic: a Dutch oven or skillet might be used for everything, and a spoon, fork, or even a simple stick could do the job. The usual stove was a small pit containing a fire, and many people who began with cast iron stoves discarded them because of their weight.
