.... this is especially the case with runway 2-20, both of which exist on most
airports for which one exists.

I once flew to an ratehr rundown airport with a 2-20. The Unicom was
so badly garbled that I even after asking Unicom to "say again" three
or four times, I had no idea whether the guy was saying "zero two" or
"two zero."

No wind tee, wind sock to bedraggled to make out from pattern
altitude.

Based on winds in the general area, I suspected he was saying "zero
two" so I asked him "Runway 2?" and he came back with the same number
of garbled sylables as before.

Hearing no other traffic after two circuits, I finally just landed on
runway 2 and tried to teach the guy how to announce runways.

Had he said "Runway two," I would have known from the number of
syllables which runway he meant.
