I'm a fan of bridges, and when in Sydney - this is the one to shoot.  Ideally you get a stellar sunset or a gorgeous blue hour, but either way, get over here and fire away!  :-)

For my trip to NYC, I had a list a mile long of things I wanted to shoot, and the Brooklyn Bridge was very near the top of that list.  While I didn't make it to all of them, I made sure I got here, and it was worth it!
