I'll tell you what is a really neat map trick (albeit, expensive). If you can find someone with a color plotter, you can take and print a topo map to Tyvek, and convert that Tyvek to an extremely lightweight ground sheet. You then have a combo LARGE SCALE map of where you are going plus a ground sheet, all wrapped up in one. Tyvek is printable, and if you physically roll it a lot (some people throw it through a washer or tumble through a dryer on air setting with shoes or something) it becomes soft like cloth. I heard (fourthhand) this may be used in the US military, in Special Ops or other applications.
