In July 2016, I went on a geocaching tour of NW Minnesota and NE North Dakota with Quilting is fun too, oakwilt and JABIE28. QIFT picked up a TIDBITS flyer in Grand Forks and I found it in my car after the weekend was over. I knew that someday I'd make a puzzle out of the TIDBITS article. Two years later, I finally got around to creating the puzzle.
