If I could go back anywhere in time, it would be from that era up to the early 30s, assuming I could avoid the war. . . and the depression . . . and the influenza . . . well, okay, I'd be real careful, armed with a detailed history book and lots of local currency. I would want to visit with Einstein and then peruse all the book stalls and newsstands, and then, and then . . . I dunno, shoot Hitler or something.
