A friend and I went driving past Theroux' Pupukea house a number of years ago just to see it (my friend hadn't realized Theroux lived here), and it turned out he was in the front and graciously invited us to chat for a while.  It certainly didn't hurt that we were both avid fans of his writing.  After reading his comment that, in effect, he doesn't have much of a following here -- I'm glad we had the opportunity to demonstrate that we may be few but we're faithful.
