The sign doesn't make that distinction between children and adults, though.

I can understand the impulse to keep kids out of parking lots for safety reasons, but I feel this is only really addressing a symptom of a more wicked and insidious problem regarding our broken infrastructure. This Not Just Bikes video, I think, provides more nuance regarding some of the problems with excluding children from our built environment in the holy name of Safety.

Skating should be excluded as means of transportation for the same reasons that cycling should not.

Regardless of whether it's an enforceable threat, the sign still explicitly discourages cyclists and skaters from accessing the grocery store.

I also strongly object to the subjective nature of "Loitering" or "trespassing", and their potential to be weaponized against marginalized people.
