No, not Longford...

Catalina was 1m 512yards IIRC, Oran Park's longest version was about 1.6 miles, so I'm talking about two straights on a circuit each of over three miles. Longford was 4.5 miles, but that included three long straights with the longest about a mile, though it did have a good long windup with a very shallow corner onto it.

Neither of the circuits are in Australia. As I said about the first one, there's clues in the trees.
