We continue upwards without exertion or danger. S uddenly we're at the top. Evidently there are no aficionados of American cinema among us. Now 10 more people silently size me up as shark bait. A tri-mast timber sailing ship, like that captained by James Cook when he discovered Australia 200 years ago, magically appears and glides underfoot.
Truth is, it's all a big yawn in terms of danger.
I've felt more anxiety riding a lawn mower. But I do feel small and insignificant up here. Small though we may be, the peaceful panorama engulfs us and makes everything seem right with life. The world simply looks better when you're atop it. Climbing a bridge will do that to you.
