You are preflight planning in the morning before an afternoon flight. Where would you find information regarding an "Airport surface hot spot?"

Explanation

Airport surface hot spots are published by the FAA in the Chart Supplement, which lists each hot spot with a description, and are also depicted on airport diagrams. They are a permanent charted feature, so you look them up in the Chart Supplement during planning; they are not normally NOTAM items and Flight Service is not the source.
