Based on the ideas on a similar thread from several months ago, I now carry a couple of maps in my wallet. Two sheets of waterproof paper, with local area maps front and back. Lots of addresses hand written in very small print in the margins. Totally illegible without glasses. Waterproof and after several months in my wallet, no signs of wear. The least useful part of the least useful map is folded to be on the outside.

I know how to get from A to B many different ways using my normal means of transport. After the Big One I'll likely be on foot and normal routes may be off limits for whatever reason. I could carry a GPS, but that's much harder to fit in my wallet. Not what I consider EDC.
