In the past, I've routinely installed and used Microsoft Streets and Trips to find places and investigates driving routes and alternatives. However, S&T is not the only game in town; Garmin, deLorme and others make route mapping applications. The web site Laptop GPS World is dedicated to this class of product and has many useful product reviews and discussion threads about the pros and cons of one product versus another. However, I'd like to hear from the folks on this forum. If you use mapping software, what do you recommend and why?
