Work hangin' in like Gunga Din

Any writer who has written as steadily and as long as I have will end up with a large body of work. Most of it comes and goes -- a year down the road, it's forgotten. But some work lingers, and when you go back to it, you're proud to own up to it. These titles are in this category. Half a century of writing, a "keeper" every six years or something ha ha. Not bad at all.
