Way to go (preposition with fun)

I travel by car,
I travel by train
I am in the truck,
but on the plane.

I travel by bus,
I travel by van,
I travel by any
li'l thing I can.

I travel by sea,
I travel by road,
I travel by rail
to be on board.

I‘m on the bus,
I travel by air,
I’m on the train
but in the car.

I’m on the ship,
and on the ferry,
I go on foot,
I travel by lorry.

I’m in the rowboat,
in the helicopter,
I'm in the auto,
but on the scooter.
