4) Right then, there were families with kids sailing around the world. They were
visiting Istanbul, Tokyo, Dubai, and the lesser known Dalap-Uliga-Darrit in the
Marshall Islands. Some wrote books for a living, but most saved up funds in

to land only long enough to work in order to save up for the next offshore
journey.
