So your my brother from another mother, haha, i have small game traps, 5 inches and a chain, never ate a Pigeon but good to know, they are everywhere, food is all over, i have seen crawdads in dry creeks at the right time at night here, Im in the hill county just west of Austin, could bag a deer no problem on my property, im used to mule deer out west that are huge compared to tx deer.
Van peeps are close but most of them would be screwed beyond 2 weeks if they just got done shopping, if shtf at the wrong time they might have 2 days of food and water and a 1/4 tank of gas.
I have worked for the government for a long time, DOD, i have seen all the war games scenarios, we are very vulnerable to one attack vector, its almost amazing it hasn't happened because its really easy to pull off, a nuke from NK would cause fewer deaths, more initial deaths but fewer in the long run.
As seen by the last hurricane in tx and the whole state not having gas for 3-4 because of a run on gas stations, if something really happened nation wide you wouldn't have food or gas for weeks.
When the system breaks down you get this
