Yes , you are followed BTW ; I have a lifestraw. also in this grab bag it is an urban bag so I do not carry cooking nor metal cup. In my larger pack I carry compass, metal cooking cup, flat stove and fire starting, I ensure i have five different ways of making flames. But for my urban environs I never carry ignition sources. I carry 20 dollars on my dog tags of contact info around my neck, silver and gold coins are available in the house. These are ultra high grade collectibles so they maintain an investment value, but should we find ourselves drawing down on the Apocalypse we will happily sell them for our survival . . .
Metal coins ; I wonder if I mentioned them to the tax office in my last audit . . . : ) [ just kidding ] ; )
Also a few bitcoin in the phone is a good thing in my opinion. I travel a lot and there is always a possibility of facing a problem getting home. The coins would not be my first choice, I wuld try http://www.abitsky.com/ first, then if not possible go to back to basics, real money.
