He’s in the tri-state area, of course, like almost every other American (well, except for those in the Four Corners area). What you probably meant to ask was which tri-state area he’s in. Every grouping of three adjacent states is called “the tri-state area” by the locals.
Well, only if it’s anchored by a major city, e.g., New York-New Jersey-Connecticut around New York City.
I imagine that the Ohio-Kentucky-Indiana confluence anchored by Cincinnati might be called one also. Chicago’s metro area could be said to extend to Indiana and Wisconsin, but the natives refer to the area as “Chicagoland”, not “tri-state area.”
What other areas could the term conceivably refer to?
It’s also pretty common in the Philadelphia area for it to mean Pennsylvania-New Jersey-Maryland. Which really confused the Delawarians, who thought it meant New Jersey-Maryland-Delaware. And around here I’ve occasionally (though not as often) heard it for Montana-Idaho-Wyoming.
Living down under I have seen a couple of fleeting glimpses of platypus but they are pretty hard to spot and this comes from someone who goes bush a lot!
Wombats, Tassi Devils etc are pretty common and not hard to spot at all.
I was also at Toranga Zoo in October. I saw the platypus also. We got a pretty good look since it had buried a carcass of some sort of crustacean in the rocks near the front of the tank, and went back looking for it. I was surprised by how tiny they were, I always thought they were bigger, and also it was very quick. We came back an hour later and it was nowhere to be seen, though.
When I heard “tri-state,” I actually did initially think of Wisconsin-Illinois-Indiana, being a Chicagoan. It’s not the most common term, (though it’s not rare, either), but we have I-294, known as “the Tri-State” or “tri-state tollway,” and I do use the term “Tri-State area” to refer to these states but beyond the more geographically exclusive “Chicagoland” area.
Not to threadjack, but what’s the point of zoos if they don’t capture or buy non-endangered animal specimens? After all, if zoos only existed to run breeding programs for rare animals then allowing the public to visit only gets in the way.
