I disagree. If you look at a sectional, you will see many different symbols
representing the various kinds of airports.

The different symbols that come to mind a

Color coded - blue vs magenta.

A solid circle vs an empty circle, indicating paved vs unpaved

With 'nubs' vs without 'nubs', indicating fuel available vs fuel not
available.

Therefore, I submit there are eight different 'kinds' of airports:

Towered, paved, with fuel.
Towered, paved, without fuel.
Towered, unpaved, with fuel.
Towered, unpaved, without fuel.
Non-towered, paved, with fuel.
Non-towered, paved, without fuel.
Non-towered, unpaved, with fuel.
Non-towered, unpaved, without fuel.

Unless you consider lighted vs unlighted, which would make it 16 kinds.

Or maybe open vs closed - making it 32.

Any of you who have thorough knowledge and understanding of
Airports will know that there are only two kinds of Airports in all of
our National Airspace System (NAS). There is Towered and Non-Towered
Airports.
