Actually ocean going tugs sometimes push. They have special barges

Interesting. I've never seen that. I'm on an inland river, and all our
towboats look like this: http://blizzard.zmm.com/tug/capned3.jpg
And they always push, never pull.

I live in Iowa. The state is between two big rivers with barge
traffic. I call them pushboats.
