Most Detailed Road Atlas?

[cloudberry]

Hello,

I have just recently joined the forum myself, despite lurking in the background and reading the interesting discussions and useful tips for a long time. :)

Our road coast to coast trip for 2012 is still in the early planning stages, so I will probably come back with numerous questions in the future. For now, I would like to ask for some advice regarding road atlases. I live in Europe, and unfortunately, the bookstores in my city do not carry a large selection of US maps - which means I'll have to purchase a road atlas "blindly" over the internet. Despite all the reviews on Amazon, I have a hard time deciding on which atlas to choose - and I wonder if someone here would be able to recommend a good US road atlas based on first hand experience. I would like it to be spiral bound, as detailed as possible (I do realize, however, that no road atlas covering the entire USA is detailed enough, and I probably need separate maps for each region) - and preferably have a grind system so that you can follow a road from one page to the next, instead of having to refer to the index every time. We do have a GPS with US maps, but I still love having a good "old fashioned" road atlas to use as well. :)

So far, I have found the following atlases:
-Michelin Road Atlas 2011
-Rand McNally Road Atlas 2011
-AMC Road Atlas 2011
-AA Big Road Atlas 2011

I would be thankful for any advice! :)
