Occam's Razor hard at work in Golden Gate Park this morning.

Me walking past the tennis courts: Hm, why is there a big crowd of people standing around awkwardly at 0730 in the morning?

Me walking along JFK: Who is this bozo driving their car along the car-free part of JFK? Oh, there's a big decal on the side of the car. "Laver cup?" What is that? Are they advertising something like a Stanley Flask?

Later on, I'd get on the internet and find out that the Laver Club is a tennis tournament, and I was watching some tennis official gradually figure out that they'd passed the place and were lost and late.
