i custom made a map using http://www.mytopo.com/
They sent it in paper form.. Otherwise the Chiniguichi area would have required more topo maps.. Custom making your own potentially could save you money and maps..its annoying to carry a full sheet when you need one corner.
Another option should be to go to the library and use their computer to print the Ottertooth maps of Chiniguichi. Then run to your office supply store and have them laminated. I was able to fit them into a handy letter size sheets.. no more blowing away of the big map.
Or save the data from your computer on a memory stick and go to the office supply place and have them print and laminate.
