W? I've never seen that one. I know Z is complete anarchy, so W would be active warzone?
You don't see 'W' too often as most of these maps are of cities, and generally don't have natural wild spots in them

(no, the lawless Z zones don't count).
These are the areas that are totally devoid of settlementation..... usually cause there is nothing there to support a city, is too remote, what have you...
Basically, its the undeveloped areas between megaplexes.
Look at a map of B.C Canada. Any where there isn't a town, its woodlands, mountains, remote streams and valleys. Less then 30% of B.C is developed, just due to the terrian up here.....
To put in as much cellphone coverage as we have, it has required crews like mine heli-jumping onto remote peaks to set the towers. There are 6 towns *that I know if* that are completely 'off the grid'. No electricity, no running water (or plumbing!).
These are the areas that get a 'W'..... And in case you were wondering, if you are in these areas in SR, and you have an emergency, both KE and Do Wagon list this as a "Not Our Problem" call. Meaning, no help.
