As a four year old, my child loved playing "the subway game", which is similar to this but just in our heads: I name two subway stations and he tries to think of the fastest route between them. When that is exhausted, we move onto the fewest transfers, the most convoluted routes, the 1968 lines only, etc. There's just something about the NYC subway which really draws kids (and many adults) in.
