Oh yes lots of time every few months i go on a ferry ride , and last week took my cousins on a ferry ride from Darling Harbour to the Quay and last friday night took them for walk on The Sydney Harbour
Yes, under the bridge on a lot of ferries, & also under, on 3/4 cruise ships, which have left the port at 6pm, during daylight saving time, but of cause not the ones that sail from Circular Quay!
I was also on the middle of the Sydney Harbour Bridge on the 25th January 1988, & looking down onto the tall ships. An amazing sight, as they
sailed under the bridge. I could NEVER make my self climb it though. Of cause iíve been over the bridge by, bus, car & train. Iíve also walked over the bridge, right down the middle of it, & also in the tunnel, under the harbour. It does help of cause if you live in Sydney, like I do.
