Like for example, I know people who make it their goal to visit every NFL/MLB/NBA stadium or arena in the US because one, they have interest in the sport, and two, it allows them to visit cities and states they normally wouldn’t visit.
I’m not interested in sports at all, so I’m wondering what other ways there are to do that? Like “I want to visit every ___ in the US” but I don’t know what to fill in the blank with
