Got a kindle for christmas and haven't put it down since then whilst reading Game of Thrones. I first bumped across the author reading the Wild Card series. Great map. How about marking the dragon roads. I seem to remember Tyrion hopping out and noticing that they were melted sand or rock elevated and barely worn even though well travelled. Can't remember if they were left there before the Doom of Valyria or not but it would probably be something someone with a map would like marked.
