Here's me talking to Lorenzo Langstroth's great great granddaughter at the American Philosophical Society building in Philadelphia. No, I couldn't convince her to take up beekeeping. We missed the plaque dedication, but did manage to drive past Langstroth's house on front street after circling downtown Philadelphia and a brief sojourn into NJ. You can drive into NJ for free, but you pay to exit. Next thing you know, they'll put up an iron curtain to keep them in.
