Using your other prepper gear and supplies you have survived the onslaught of SHTF day! With your bug out bag you managed to make your way to a relatively safe, remote location where you could survive for months, years or possibly even indefinitely. But most doomsday scenarios will eventually subside – some semblance of normalcy will return to mankind and your lot-in-life could be improved if you return. But at your bug-out location way up in the mountains you have no way of knowing that government has returned providing resources and that society is starting rebuild – unless you have a reliable way of communicating with the outside world.
