Yes, that is an embarrassing faux pas that has been pointed out by SEVERAL people now. The caption was written by the author and none of us caught it. As you said, not the worst thing in the scheme of things…and not the worst mistake we’ve ever made, but embarrassing all the same. Just goes to prove that humans still work here!
Does anyone remember the worst typo ever? Hint: it was in a Don Thomas editorial (a long time ago).
