I'm from the Bronx, NY. My survival skills are a bit different than yours, but I concede I wish I knew more of yours.
Man, if only somebody would pass concealed carry in NYC...
I just read your profile -- you've got what it takes! Why not volunteer to help out a local Scout troop -- you'll be amazed at what the boys (and their leaders) can teach you! '-)
FWIW, survival is mostly an attitutde: "I ain't gonna sit down and die. Now, what is there around here I can use to help me stay alive?"
Example: I'm not from the Bronx, and I never considered urban survival before -- but it wasn't hard to imagine what's in a city...and realize that every toilet has a flush tank full of clean water...
Good luck!
