There are some nice software packages out there from "National Geographic"....and they will run you around $100 U.S. per state.

There is an outdoors store in a neaby city that has a kiosk that you can walk up to....use a touch screen interface, and then print off a 1:24000 or 1:32000 map on water/tear resistent "map paper"....and, it prints off on a legal size page with whatever point you want at the direct center of the map. They run about $8 a piece...but pretty nice since the area where my family's cabin sits is on overlapping topo quads....much less bulky than carrying two..

It is so easy to become disoriented. A couple of years ago my brother shot a deer on some of our land, and it continued running into the woods off of the SE corner of one of our fields. We tracked it for a ways into there.....darkness fell....cold, drizzly November evening.....and we got turned around. Fortuntely, I had a little Brunton keychain compass...whipped it out....and knew that, if we headed NW or N, either one, that we'd run into our property or a known road. Any other direction would have been a LOT of walking. (We found it, and it was tasty, by the way.)
