Most people live in homes that are firmly fixed in one spot. They may be huge apartment
blocks or small private residences, mud-walled huts or houses on stilts, but they are alike in that
they are not easily moved. For some people; however, who like to wander, a permanent dwelling
is a handicap. They prefer a mobile home, one that they can pick up and take along with them on
their travels. Tents are conveniently portable, and for many centuries they have been a favourite
form of shelter for nomadic tribesmen. Tents are also frequently used in military operations, and
on ordinary camping trips. Other types of mobile homes, such as caravans or houseboats, are
roomier and more comfortable to live in than canvas tents.
