On Tuesday, while setting up for Puzzled Pint at Beulahland, we managed to lose one of our answer sheets while stuffing puzzle packets. I quickly made an extra one by hand, just in case a full complement of 20 teams showed up. (They did, though two of them ended up joining forces with other groups, so we only got 18 answer sheets back.) Good thing we had plenty of scratch paper.
The scratch paper I used was actually an unused puzzle from a previous month. Guess which one and I'll send you a prize!
