This map is small: 4x3 feet. I would like a large map, maybe four times the area (8x6 feet), but with the same density of information. One could represent four times the number of towns, streams, roads, etc. I want to hang it on a wall, and be able to read it for hours, always discovering new places to visit. Anyone know of such a map?
