Heights--so I joined BALCLUTHA's topsail crew, and now I get to climb 60 feet into the rigging and balance on a rope about two inches in diameter. Of course, it took me about eight months to get up there, and I'm still inching my way higher. A friend observed that I shouldn't worry so much--after about 20 feet, I'd be killed if I fell anyway, so what difference does another 40 or so make? Fortunately, the ship is tied up and doesn't move much.I still can't walk over the Golden Gate Bridge.
