Until the pandemic, I often on an unoccupied weekend walk down to the local bowling lanes and roll three or four games. One time I decided to try it with my Worldcon 76 shirt, and discovered that they aren't really bowling shirts; they don't "give" quite right. But they do look like they should be bowling league shirts, and it would have been fun to have SMOF Bowling. (I can't say that I'm any good, although I was starting to improve sufficiently to consider signing up for lessons, which included the purchase of a bowling ball. Maybe if life ever gets to the point where I feel safe going to the lanes again, I'll consider it again.
