The crush of sightseers, known as overtourism, has grabbed headlines across the world.

On a woozy Monday afternoon, those sightseers who had assembled on the tower's second-floor viewing platform discovered a clever ruse: the telescopes could be used to spy on a beach volleyball match happening down below.

On a visit last week, with only a trickle of foreign sightseers and a few locals around, the town’s cobbled streets, mock-Tudor pubs and quaint tearooms were eerily quiet.

The intangibles include selfie requests from blue-clad Wildcats fans and the occasional sightseers who drive slowly past their house as if a celebrity lives there because, well, it’s Kentucky.

The passengers can be divided into three broad types: car people, deck people and sightseers.
