Dooley, Rhine, and Davis not only treated the people in Muong Sing and those from the surrounding areas, but they also went on river trips to take medical care to distant villages. One trip took them down the Nam Tha River in December 1958. They hired four or five dugout canoes, or pirogues, to carry them and their medical supplies. They floated down the river until they came to a village, they stopped, went ashore, and held "sick call" for a day or two. Then they floated down the river to the next stop. This went on for two weeks.

          The Lao government was pleased with the first river trip, so they encouraged Dooley to deliver medical care to other people through more river trips. Dooley and Davis went on another river trip in February 1959.
