This is likely the last engineering-themed crossword puzzle
that I will be creating. It takes about an hour to make and publish each one, and since I suspect the number of
dedicated cruciverbalists out there are few, it is just not worth the effort anymore. Without any memorable exceptions,
I have created a crossword puzzle every week since sometime in the year 2000 (more than 700
total). Each one was made with personally selected words to avoid non-relevant terms and clues. The puzzles
will resume if enough requests come in to do so, otherwise, today marks the end of an era.
I will still be glad to create a special edition crossword for your newspaper, newsletter, etc.
