Johnny Cash spent much of the 1950s and 1960s addicted to alcohol, barbiturates and amphetamines. Whilst we should assume he was probably familiar with contemporary work on finding shortest paths in weighted graphs, and almost certainly read the papers etc, it is likely that his addiction kept him from paying the proper attention that he would otherwise surely have done. Who knows how different the landscape of theoretical computer science might have been, had Cash spent more energy on algorithms and less on setting fires inside camper vans?

I'm not sure if he would have covered that kind of material during his time with the Cryptographic Intelligence Unit anyway.

One of the best trivia pieces I have is that he is likely the first American to know Stalin died while he was posted in Germany, decoding morse code traffic.

Also, tours depend on a lot more than travel. Venue availability, other major events impacting attendance, advertising and marketing.

Travel optimization isn't really a priority.

Yep. Seattle was an often missed point on the map for tours, until the punk/grunge evolved there. Then suddenly you couldn't stop people from driving that incredible distance from LA
