My guess he would go anywhere that would pay him, as long as it didn't take him too far from home for too long. And he would be polite and churchgoing and call every course he worked on one of the best in the country. He'd be loathe to criticise someone else's work but would have firm opinions if you listened closely enough.
He actually designed at least one resort course, at Rosapenna.
There is one post war architect that I suspect closely resembles Old Tom in personality, and in his approach to GCA, and that's Eddie Hackett.
Another thing he would recognize is the influence he has had on greenskeeping.
