A friend and I used to play "adventuring" on Saturday afternoons when we lived in South-East Asia. Take a couple of coins for buying tickets, hurl yourself on the next bus that comes along, then the next, and see how far you can get in an afternoon. No distracting fixation on destination, no worries about getting home (taxis were cheap).
All around town we would scoot in a kind of peaceful trance, watching the city through dusty windows. Past financial centres, dusty street markets, suburban housing estates, historic monuments, over bridges and down back lanes. Sometimes dull and sometimes enthralling, these erratic peregrinations took us to places no tourist would ever see.
It seems that attaining the sublime confidence of the regular passenger is a matter of either strict planning, grim experience, or simply going along for the ride. It doesn't do to be too fixated on destination. Public transport is, like love and life, about not only anticipation, but surprise.
And just to finish off what has become a transport theme this week, there is currently the Public Transport Challenge being staged in Melbourne. It is an orienteering event for teams of high school students using trains, trams and buses to reach destinations quickly and efficiently, and gathering points which will determine the winning team. Sounds like fun!
