My apologies if I unduly credited you. Actually, TRSA's were first mentioned
in the second message on this thread. I simply felt your message was the
first to directly address TRSA's, as opposed to simply referencing them.

In the body of your message, you stated: "TRSAs are a lot rarer than ASRs".
However, as has been noted, The Chicago Sectional shows one ASR and three
TRSA's, which would contradict your observation.

But, given that aviation facilities are unevenly distributed around the
nation, I would not find that surprising!

Please review the subject of this thread, which is the use of an "R" in

circle on Sectional Charts to denote the presence of Airport

Thread drift, it's called :-).

It appears Mr. Reid introduced TRSA's into the mix, a point I failed to
note.

Erm, what?! It appears Ron Natalie, in
om, introduced TRSAs
into the mix, a point you failed to note:

One thing that VFR's should note, that while participation is
voluntary
in the TRSA, many TRSA towers get a bit testy if you don't go in
through the TRSA-approach control.

That was included in the article of mine that you responded to. And it
may have been introduced earlier by someone else -- I didn't follow the
references all the way. I just happened to notice the reference to
TRSAs, and started wondering...

And it appears that a TRSA is not the same thing as Airport
Surveillance Radar.

Well, no -- TRSAs are a lot rarer than ASRs. Which is why I asked the
question about TRSAs (having never actually encountered one myself).

Such is Usenet, I guess.
