Ah, yes, posting in QF would have been a good idea. But that didn't even occur to this UA/*A people person.
In any case, I DID take the train down to Circular Quay and wandered around. Was fun. Stopped into the MCA. And walked out to the Opera House. Was neat to see that icon up close. (Too close, really: I didn’t watch out for the outward sloping glass at the base and smacked self in the head, much to the amusement of the workers inside.)
