“Next thing I see is, they hanged the colored boy, ’cause they caught him stealing. And they had established, I think, about 1,000 trees in the forest out in Mark Twain to hang people from if they catch them stealing or whatever. And I had a big dog—my dog died of bone cancer of all things two years ago. Buddy was half-Rottweiler, half-German shepherd. He was a dog, and he was with me in this. And I also have a police riot gun, a 12-gauge, that holds eight magnum shells. So I’m seeing all this stuff happening, and then I look around, and my dog’s gone. So I picked up my shotgun and went to look for my dog, and I found five men, and they were already skinning him to eat.”
Newer innovations have allowed mobile phone users to still communicate in recent floods using the GoTenna devices, which are paired with mobile phones to create their own mesh network and communicate without needing a phone signal. These are much more limited in range than HAM radios though and only have a 5-7 mile reach. It is possible to send a message further but that would have to be through the meshing or ‘hopping’ through these devices.
Is it stereotypical that the AARP crowd would be the ones to spend three hours talking about metal detectors and canning and caving at a Pizza Hut on a Monday night? Probably, but that’s what I bore witness to in this event room; its combination of exposed wood and stock-photo decor felt like an Olive Garden inside a pirate ship. Up front, the scraggly white-bearded, Bad Santa–lookalike Andrew: rested one foot on a chair, gripping the mic, just like Randall said he would be. 

What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
