This is also not a reading but it is really cool.

This program shows all the places you can travel in a given time by a variety of means. Select your trip time and you get a nice slime-mould-like blob that shows the furthest places you can travel, stretching along whatever roads you may take from your starting point. Here's an explanation:

Anyway, I love this thing. It's the perfect illustration of how fucked suburbs are.
Go to Winnipeg. Click on "show pedestrian". Trip time doesn't really matter but I like 6 minutes and 2 is too short. Now click on some point in the Exchange. You'll see a dark blue blob in the middle of a lighter blue blob. Now, try the same thing in a neighborhood with a long grid layout like the West End or River Heights. See how the blue blob gets smaller and distorts around the grid? Now click on one of those nice little culdesacs in Linden Woods and observe how you can walk fucking nowhere.
The funny thing is, the big, light blue blobs represent driving distance. The great irony here is that the car-dependent start point (Linden Woods) has a smaller reachable area than either urban location.
