Warchalking

Warchalking is the practice of marking symbols on pavements (sidewalks) and walls to indicate the presence of nearby open wireless access. It was supposedly inspired by the practice of Hobos during the Great Depression to use chalk marks to indicate which homes were friendly. Warchalking is now rarely encountered, since many WiFi networks feature automated security.
