```My comment was about "most geographers".

Alan probably has in mind what was not
explicit -- that I am formally (or perhaps
was formerly) a geographer. However,
I am not necessarily typical of "most
geographers". Nevertheless, the answer is simple.

You use a name. For example, I can get to
NASA, Houston, TX -- with some help from my
friends -- without using any numbers whatsoever.

This is not a technique I recommend to NASA.
To get to Mars, for example, you should use numbers.
