Why 2 different set of maps.

I carry the GPS map only in my GPS?

The Memory Maps are printed and serves as my primary source for navigation.  Of course, I've tweeked the colors so that they taken on an appearance very much like Fisher maps (yellow land mass, blue water).

My printed maps are on 13 X 19 inch waterproof paper, which fit my map case near perfectly once folded in half.  Of course, I print on both sides of the paper to save weight and space (and to same on paper ... its a bit pricy).
