Damn. I hope that doesn't somehow affect my paper maps.

The only thing that might affect your paper maps is the unexpected
faster movement of the magnetic north pole.

Rain.

Wind, too, although I expect rain makes certain display screens difficult or impossible to read.

What maps give you is a better understanding of your over-all position in the world -- rather than a postage stamp sized "you are here" map. If you zoom out, you often lose your frame of reference or details get so small that they are useless (road names go away, etc.). The only thing worse are step-by-step riding or driving instructions. You make a wrong turn or get accidentally funneled off a highway by the off-ramp from hell and your're screwed. You need a regular map to figure out how to get back on course. People should also learn to read maps -- just in case the power goes out or batteries go dead. They should also have a cross-bow to shoot zombies when the power goes out because zombies are associated with power outages.
