I disagree Blast!! Think about the basic tactics lessons that was in "Lights Out". I live in the same situation that you do. The real problem isn't defense. The two real (insurmountable) problems are: FOOD and FEMA!

On defense: map out the neighborhood and and look at your access points and other weak areas. Build a defensive team (1st string/35 & older years) that patrols those areas/points. Build 2 reaction teams (2nd string/18-34 year olds) that responds where the initial attack is coming from and a reserve to counter a flanking attack, build a last ditch team (3rd string/women & all of the 15-17 year olds) to protect each homestead and provide bodies for OP's & LP's.

Water can be used from the swimming pools to flush the toilets & provide drinking water. Rain water can be corraled back into the swimming pools and/or buckets/barrels.

VERY LITTLE FOOD can be cultivated on the average subdivision lot. That is the problem!

Energy availability will be another issue. Gas, Diesel, firewood, etc.

As mentioned in "Lights Out", the presidents have signed various executive orders & PPD's that allow, in time of emergencies, for all civilian resources to be confiscated (to be doled out to people in shelters) *(More than 3 days groceries and supplies in a household constitutes "Hoarding")* and 10 concentration camps (I mean "evacuation/detention camps) have already been constructed around the country, during the last 10 years (mostly in National Guard Camps) (the govt claims that they are for teaching the military how to survive in POW camps although no one has ever trained in them), and a $350 million contract was awarded about 8 months ago to build 10 more camps. 1 of those camps are to be built outside of Natchez, Ms (the locals are fighting it). FEMA "Crisis Relocation Plan" is just as the description in "Lights Out". If you remember some comments I made a few months ago about the New York City "Crisis Relocation Plan" that came into being in the late 70's and what a complete farce it was and is.

My solution to the problem is to first organize the neighborhood and dig in. Sometime along that line, if serious trouble erupts in town and I feel that Martial Law is about to be enforced, I will advise my neighbors to prepare and plan for Bugging Out. My first stop is just to the west of my present location in order to regroup and reassess. Then the next move is to get to Northwest-Central Arkansas where I have some supplies cached and people who have need for my skills, Library of knowledge, and those resources that we bring with us (includes walking, talking, thinking, bodies). I have put several realistic contingency plans together and I periodically review them (just completed a review of all contingency plans, wrote a few more to cover other aspects of those situations).

You might consider making some acquaintences around Lake Livingston and/or Sam Rayburn Reservoir. Those are far enough away from the cities, withing a reasonable transit time, and there are defensive areas there as well as cultivatable land.
