This is a map of the Seattle trolley system in 1933. Why?
A: In case you go back in time, or are messing around on the holodeck and need it.
B: To remind everyone that we used to have a public transit infrastructure that was subverted, destroyed and then forgotten. This is applicable now. Look at how our cities (don't) work. We are told or not told or left to think that it all happened that way and that to change it would be, at best difficult and at worst against the American spirit. Not to be confused with American Spirit. Apparently the American spirit was conceived in the back of a Lincoln Town Car in a mall parking lot. We can do supertrain and baby supertrain because we did do supertrain re-remember the lessons of our past.
