I noticed in the new New York Sectional (just came out a few days ago)
that the Smoketown, Pennsylvania (just east of Lancaster) has a new
identifier, S37.

Ok, identifiers change sometimes, but a few years ago Smoketown changed
from 37PA to Q08, presumably in the effort to make public use airports 3
digits.

Now it changed yet again...why? Was there a problem with Q08--perhaps
being confused with somebody else in the area? (Most one letter- two
number airport IDs in Pennsylvania/ NJ begin with N.)

Looking further, a bunch of Q-number-number ID's have changed recently to
something else. Perhaps the FAA no longer likes identifers that begin with
Q? Still its strange that they just assigned one to Smoketown a few years
ago only to change it now.

Here's a bad one, 6PA4 (Morgantown, PA) became O03. (That's letter
O-Zero-Three.)
