I think I will settle for going up on the Sydney bridge pylon or perhaps walking across the bridge on the bottom. I do want to see the flying foxes in the botanical garden. I wonder is it better to see them depart at dusk or come back to roost at sunrise? I think jet lag might have a roll in which I see.
I don't think I could handle a bungy jump, the whole upside down thing would be too weird and I'd be afraid my eyeballs would pop out. (actually, retinal detachment happens not infrequently). There is a jump of a sort in Queenstown where you swing out over the town from the nearby peak. I still think I'd be too chicken!
I'm nowhere near as brave as Karen and Marcie!
