Bottom line...GPS device is a good investment...even the $150 TOM-TOM 140S...small screen, street names, easy to use and transfer from vehicle to vehicle, even if you "pack" it and only consult at rest stops/gas stops. Having a trip planner (from AAA) is also a nice thing, IF you are into rigid planned schedule type guy...they are VERY handy, store easily and just flip to the next page on your route, can't be any easier than that.
