We never hear about it, but when the wagon trains were working their way West, the folks must have had to find some way to, well, take care of their bodily functions. The men, of course, because of their somewhat different physiques, might not have had much trouble taking care of business, but for the women it was a different story. Crossing the vast plains of what is now Texas, Kansas, Nebraska, and then the great deserts of the West with nary a tree or bush in sight must have caused some concern. But we never hear about it, so those hardy folk must have found some way to preserve their dignity and their privacy.
