Today's black and white photo is of a group of people walking to the top of Sydney Harbour Bridge. This was taken from across the harbour outside the Opera House with a lot of zoom. I have never climbed the harbour bridge, but I believe it gets pretty windy up there.
Haha, I put a photo up a few days ago of people climbing the Story Bridge. This is great, you can see how high it is. I've done the Sydney climb twice, and I can highly recommend it. Such an amazing view from the top.
