One thing you might want/need if/when SHTF occurs is maps of the area where you've gone to ground. Give this a look:

Thanks, Top. Just saw that over at Northwest Firearms--where was this back in my RR-history days?

Many of you are probably already aware of this, but no internet connection is required to get GPS position and altitude on an IOS device, as long as it has a cellular antenna. (All iPhones obviously do, and it's an option on iPads.) An app that provides this info is the perfect companion to these topo maps.

The app I use to provide raw data is AltimeterGPS:

Incidentally, if you're traveling to a new city, an app called CityMaps2Go takes advantage of this GPS capability. The idea is that you download a map of the city before you leave home (or the hotel), because once you're outside you won't have a reliable internet connection. Then, as you walk around the town, you get a moving blue dot on the map indicating your position. I've used this app to navigate twisted streets and back alleys in many European cities, and it's incredibly accurate; it's not uncommon for locals to ask me for directions.
