I live in El Paso Texas. There are really 2 roads in here and they are both Interstate 10. There is another highway headed north but that goes right by Ft. Bliss and would be roadblocked by the Army within an hour of any kind of breakdown. Not to protect us, but to protect themselves. That is understandable.
To the south of us is the lovely suburban paradise that is Ciudad Juarez. The most dangerous city in the world. Within city limits, 1/4 of the residents here are illegal immigrants and 80% of the overall population is Hispanic. I am a white boy who votes Republican, supports tough immigration enforcement and dispises amnesty in any form. So lets just say, I am not on the top 10 Christmas Card list of many of my neighbors.
So what do I do? I try and look for signs of a collapse or civil unrest before it gets here. I watch the markets, the gas prices, inflation, the nit-wits in D.C., foriegn and domestic events of note etc.
Should I see events start to take place, I am out of here. This is not the place to be. Nor is any city or population center. I know too many people who think that hunkering down in the middle of suburbia is a great idea. I do not. I don't trust people even when civilization is "civil". If food, shelter and gas are running out I trust them even less. I will run North a few states back to high country where there is 40,000 acres waiting for me. I'll play games on my turf.
So, if you are in the middle of the city, GTFO! Don't become meat for the meat eaters.
