Good one, tsuwm!

Welcome, Carltree. Sorry about that. I was just thinking about our tendency to make new input fit patterns we are familiar with, and yet--alder is not all that well-known or used a tree name.
Maybe they're thinking of the letter pattern of older or
elder.

Two other things: your part of the country is my husband's favorite vacation spot; and, can you tell us how Kill Devil Hills got its name? I never have gotten around to trying to look it up. (LIU, as you may have seen it here.)
