The best way of travel, however, if you aren't in any hurry at all, if you don't care where you are going, if you don't like to use your legs, if you don't want to be annoyed at all by any choice of directions, is in a balloon. In a balloon, you can decide only when to start, and usually when to stop. The rest is left entirely to nature.
— William Pene du Bois, 'The Twenty-one Balloons.'
