WiFi Warchalking

If you are interested in Wifi hotspots, as I am, check out the Warchalking website. The idea grew out of signs that hobos used to make so that other hobos would know where they could find places to sleep and eat. They started out several years ago with a group of signs showing hotspots but now I think it is evolving into a database and clearing house for free hotspots. I would draw some in front of my house but I am so far from the road that the signal would be very weak. Also I am sure I would have a rep from the homeowners assn. calling on me real soon.
Just looking at what they have so far it is obvious that most metro areas are or will be filled with FREE hotspots. For that reason Mickey D's and any others trying to charge for Internet access are doomed to failure.
