This is an APB, or a plea for help of a mild social sort, or a general bulletin-board message:

Would the nice man who snapped discreet photos of me, on board the Washington Metro, whoever you are, please get in touch with me? Regrettably I cannot recall the date -- since I didn't commit it to memory in the first place. But any information  appreciated.

Just to reassure you, I am in no way on your case. Photographers are almost as bad off as writers. I have no problem with a little unobtrusive snapshotting. Also, I have no ulterior motive or agenda and am not even slightly influenced by your being a goodlooking dude; undoubtedly you have a wife and several budding photogs at home, and I have no intention of even saying anything to you that could not be said in the presence of your mother.

But I could use a couple of those photos, depending on how they turned out. In particular, I need one for a jacket/inside cover head shot, suitable for publication in a book.

Any help appreciated. You can find me through this blog among other ways. Color would be best, BTW.
