PC World has recently reviewed Internet mapping services and GPS devices ["Sony's First GPS Comes Up Short," July; "Never Ask for Directions Again," May]. They are not always trustworthy.
Two people perished in early April in our part of Montana after using a map downloaded from the Internet. They were sent onto a road that local people know is closed a good portion of the year. They became stranded in an area with no cell-phone service and died of hypothermia while trying to walk in the snow for help.
These mapping and navigation services do not take into consideration extreme weather or road conditions. You should ask about your route when you stop for gas or a meal at a restaurant. People will certainly tell you if you are making a mistake following these maps.

Corrections
In the August Internet Tips, we should have said that the 'about:about' Uniform Resource Identifier works only in Mozilla, not Firefox.
In July's "All-in-One Security," we should have said that Windows Live OneCare does not have integrated antispam protection.
In the July Hassle-Free PC, the item on using the blind-copy feature of e-mail should have said that, in Outlook Express, the first step is to create a new message; then select View and check All Headers.
In July's "New Applications Make Backup Chores Easier" (Reviews and Rankings), we should have noted that to restore files with NTI's Shadow 3 you must use Windows Explorer.
The July edition of Gadget Freak should have said that the Philips SRU9600 universal remote control is available at Sharper Image stores.
PC World regrets the errors.
