Only need one
Here in Sarasota Florida, the downtown library has an asphalt parking lot. In Florida's intense sunshine (between the hurricanes, eh?) a kickstand can dig far enough into that stuff to topple your bike.
Most of the parking lot slopes significantly, and this uneven surface adds to the difficulty of parking a motorcycle there.
Not to worry. There is one space that is level and paved with concrete. This space is right near the main door, and is prominently marked "Motorcycles ONLY". It will hold two or three, and I have never seen it full when I needed to park a bike at the library. I guess they have accurately guessed how many Sarasota bikers can read.
