Is there a sight that shows the general layout of cities. Trying to probe the edges can be madening. Be nice to have a map that had cities plotted with X's for some of the people.

Right now I'm going crazy looking for Sherrif Green in the Hub.

You could always press tab to show a map. (At least I know you can do that in FO2, dunno bout FO1...)

See:

The police building with the sheriff in it is in the eastern part of Downtown.
