I have MS Street & Trips from 2004 and a Droid Phone that navigates via Google Maps, which is pretty slick. That said, I like pre-planning on something like Streets & Trips and wonder if I should upgrade as I start to plan a trip from Colorado to some of the parks in the Canadian Rockies. What I like about the S & T program is that it can search a radius for campsites, etc and is easy to do in advance of being on the road. Can anyone compare MS S & T to the trip planning abilities on the Good Sam's Club site? That or AAA is another route I'd consider for route planning if anyone can compare those services to MS S & T.
