[Moderator Note: Unless someone has some DeLorean-related content to add, the DR / GPS discussion belongs somewhere else. - Mike Substelny, DML moderator personally interested in the topic but doing my job] Just my opinion (not that you asked), but I find that the times I've actually needed dead reckoning when GPS alone wasn't available were VERY few and far between. My GPS works in all weather and atmospheric conditions. Unless you're driving all the time in cities with tall buildings, or in parking garages, you might want to compute a cost/benefit analysis for DR. It's really not needed these days for 99.9% of my driving. -Hank To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
