Hi Lorna:
That's a gread idea!
There is an easier method which is much the same, but accomplished with the computer. I have Rand McNally's TripMaker (got it on the Internet for about $13). You put in your starting point and ending point, add any stopovers (you can force it to take a particular route) and it will give you all the maps with text directions. There's a lot more that can be done with it including an estimated cost of your trip. It also gives you the amount of time it will take. Also, it has notes as to what page to look at in the Rand McNally map book.
I've used it for several trips including the one I'm taking to Apache Flats in a couple weeks.
I also have an old briefcase for which I don't have a need for any longer seeing as I'm retired so that is my trip case (just like an airline pilot). I have the trip report, all the campground directories, notes, and some 3x5 cards if I want to make some notations. I also have the RV Journal which I just purchased from a post on IRV2. This way, the briefcase gets from the RV to the house easily.
Oh yeah, forgot to mention. My DeLorme GPS LT-20 arrives next Monday and I'm excited about it. It's certainly low-cost at $99.95. It comes with the Atlas 2006 software as well.
