I thought I’d toy around with weighted averages to see if I had the concept figured out before I tackled the weekend’s homework. Here’s the approximate center of the transit system(s), weighted for trip origins and destinations as of the most recent data I have.


Pro-tip for cartographers: When your data is simple, throw in gratuitously pretty and engrossing things like elevation and hillshades as points of reference.
