I did make sure to tell a couple of people - my old high school principal, the woman who always calls to ask if there are children swimming in the pool, and some of the friendlier residents who have become favorites or were especially supportive of my academic career. But there are several board members who I'm sure neither know nor care that I'll be gone, and that's fine. I can't wait for them to be gone, too.
But yeah, I didn't publicize it much, so I only had one or two folks stop by to say good-bye. That's just the way I wanted it.
