Captain Kangaroo, actually. And I think they're interesting! It takes a committee of people to design a system of roads that's both practical and efficient for your everyday motorist to get to and from major cities, and yet they still manage to have gridlock traffic in most of them. I have designed a more efficient road design for places, but I doubt they'd ever be implemented because it takes years to go through the red tape, and after that, it takes millions of dollars to redo road systems.
