I was leaving a hospital parking lot last week and noticed how crazy the geometry was in the hillside parking lot.
Potholes, dips, and cracks in the pavement, and a grated manhole where water was draining into. My first thought was “Man this looks like it would be a minigolf course in TU”
Dips and potholes for dipped hazards, cracks in the asphalt could make a trough for a ball to run along, discarded tires could make obstacles, and moving vehicles. Drainholes along the edges of the street could be hazards, or even shortcuts. I did go to one minigolf course as a kid where a secret hole in one strategy for a particular hole was to putt your ball INTO the water hazard as it flowed downhill, and landed into the hole.
Maybe like a backwater street alley, or a airport parking garage for structural inspiration.
Theres a lot can go on in a parking lot, on the micro scale; to a golf ball a parking lot is a football field theres plenty of room for small details making big roles.
