This year at Burning Man, I happened to notice a car with the California state license plate "TUVA". I recognized it as belonging to Ralph Leighton, Feynman's close friend and author of Surely You're Joking, Mr. Feynman!. (The plate is a reference to the story recounted in [Tuva or Bust!](https://en.wikipedia.org/wiki/Tuva_or_Bust! https://en.wikipedia.org/wiki/Tuva_or_Bust!).) I reached out to Ralph, and it turns out he wasn't there but his son was. I thought it was a fun coincidence given the theme of the burn.
