David married a Fijian and returned to Boston to further his schooling. Gail and I visited them 1972. In 1974 he worked in Dominican Republic, where he had no paper or pencils, no phone and no mail. He said: "too many chiefs and not enough Indians".
We went out on his 21ft cabin boat a couple of times in May 1975 while he was working in Suva. After getting his PhD at Cambridge in 1980 he was in Raratonga for the UN. Over the years he has been a consultant (economic and/or educational) to governments around the world.  Fiji (Director of Economic Planning), Dominican Republic, Vanuatu, Federate States of Micronesia. Somewhere during all that he ended up with a second wife, also Fijian, and they have three beautiful children. David is down to earth. Take as an example, the time he attended a financial meeting in New Zealand for South Pacific countries. High powered government ministers, and Woody showed up in his normal, unironed grubbies. So he went to the nearest second-hand shop and bought himself a corduroy sports jacket to wear. Each country hosted a party for the attendees each night of the conference, usually renting out a large room and putting on a meal and bar. Dave joined together with a few other smaller countries to host an evening... in his hotel room. Which meant that we drove him around Auckland trying to match the bottles that had been emptied from his courtesy bar. Then there was the time when he was kicked out of Vanuatu on short notice and ended up at our doorstep with a ton of belongings. (Dave prefers to put it more positively: Contract terminated for standing on principal and refusing to recommend Vanuatu as a dumping ground for incompetent, unemployed UNDP consultants. He had been working on a vehicle right up to getting onto the plane; in fact he always has some sort of vehicle under repair.

Once established in his 1731 historic house near Boston he set about to clear the local rubbish dump of anything useful. Hundreds of skis, bikes, cars, bathtubs, sinks... all organized in his big barn and around his 16 acres. Then there was the 1800's house that he bought a for a dollar (which was consider generous) and transported to his land where it has sat on its new foundation slowly deteriorating. Where he finds time is amazing, he does have a job. He has re-roofed his ancient home, and then stripped centuries of lead-based paint from every square inch. Eccentric?? Is that the word I am searching for to describe this one of a kind? Or is he just plain interesting and colorful?
Offered $1500/month to have a communication tower on his land. He countered with $25,000/month and kinda ended the idea. In 2017 he was found unconscious - it was septic shock. He had a relative fight in the American Revolution.
