>Do you enjoy pouring over maps? Why? What's the big satisfaction/attraction?
Absolutely. I've enjoyed maps since before I could read; we had a relief topo of the Olympic Peninsula. Also, we had US and world maps on the dining room walls within reach for map races and discussion during dinner. On the smaller scale, I enjoy correlating what I've travelled over or seen with the map, and it helps bring the trip back.
>Do you put maps on your walls? What scale -- big worldly or continental scale, or local and trip scale?
I have a Raven Map of Wyoming (high-res, 3-foot by 3-foot, 3-second elevation data), and I'd get Washington, Montana, Colorado and Hawaii if I had room to display them. We have US and world maps in the hallway for the kids, along with a globe. I have a drawer full of various maps, plus National Geographic Topo! for the states in which I often hike.
>On your wall maps do you pencil in places you have been (like trophies) or places you'd like to go (like dreams)?
>Do you think of maps as inviolate?
Yup, just like books.
>Is a map consumable (used for one trip) or reuseable (used for many trips)?
That's what big-bed photocopiers are for. (Copying a portion of a purchased map for personal annotation is generally considered "fair use" under US copyright law.) I also print Topo! maps when I can, and those are generally consumable unless it is an area that I will be visiting on a regular basis--then I print on Teslin waterproof paper.
>What is your favorite map scale? Why?
1:24,000, because I can 'see' the terrain.
