It’s easy to forget that detailed maps can be made by just one person, and that paper maps aren't a thing of the past. Tom Harrison, a California-based cartographer, explains how he collects information and makes his maps, and why he doesn’t hire anyone to help him.

Artist-explorers called psychogeographers are changing the way we experience the city

A mere forty windy miles north of San Francisco, Point Reyes National Seashore is a working landscape, containing dairies and ranches that have been in place for generations.
