I can relate to that poor bus driver who got lost on the way to Bamfield with a busload of students. I've done that drive, and found myself wondering many times along the way which was the most likely outcome: That I would take a wrong turn and get lost forever on the winding gravel roads between Victoria and Bamfield, or be killed by one of the giganto super-size logging trucks whooshing past me.
Fortunately, I happened to pick up a mom-and-son hitchhiking duo a couple weeks ago on a drive back to Victoria from Courtenay, and they hailed from Bamfield. The son gave me very sound advice for staying on the straight and narrow while driving to Bamfield: Follow the power lines.
Either that or drive in sensible fashion to Port Alberni and take the Lady Rose steamboat in. Lovely way to see Bamfield.
