While others specialise in knowing engine parts or listening to
gearboxes, I had a liking for bus registrations.
List anyone of those you know, if you have one. Remember, not the
make of the bus nor the interior. Just the registration. For
example, if probably you'd know SBS 3721J (that's my 'neighbourhood
friend' who goes around serving people in Bedok), then just take
that bus and respond to the thread will do.
