It was spring of 1991, and my late wife Beth and I had just finished a six-month stint running a tiny rural hospital in an end-of-the-road town at 7,000 feet in the Himalayas of India. We’d been very isolated, and we felt like we’d been gone a lifetime, back in the days when letters took several weeks to arrive and phone calls were unheard of. When our six-month visas were about to expire, we decided to fly to Kathmandu, Nepal, to see the country and investigate any medical volunteer opportunities we could find.

Through the Western-traveler grapevine, we connected with an adventure travel organization that needed a trip doctor. It was a weeklong trek with about 50 American teenagers. They were on holiday from Saudi Arabia where their ex-pat parents had high-paying jobs in the oil industry.
