The worst place to be in the event of a complete collapse is inside a city. The first problem would be the food crisis. The larger cities have only a few days worth of food inside them, which would prompt a very hasty and dangerous exodus from the city. Smaller cities can last longer, but eventually the inability to transport food from the farms to the cities will cause panic, mayhem, and eventually starvation.

Meanwhile, out in the rural areas of the country, food panic will not be a problem because that is where the food is grown. Farm towns will not receive fuel for the farm equipment, but at least the food itself will be there. In the country people are also more likely to own large livestock that can be used as alternative means of transportation.

A necessary item to own in the worst case scenario is a firearm, preferably several of them. In a panic and riot it happens that not only are those who have stockpiled resources the subject of looting, but innocent people are often assaulted or killed in random acts of violence. Law enforcement will be too busy combating the population to provide any security, leaving it the job of the individual instead.

For those who do live in the city and want to prepare for the worst, the best advice to give is to purchase an RV, preferably a Class A or Class C (the motorized RVs.) In the event of a crisis the owner of an RV can leave in a hurry. Some people are thinking about acquiring property in remote areas, outside of easy government control. The advantage of an RV is that one can more easily transport the family to those areas, and can also move again if worried about discovery. A place to live is guaranteed no matter where one travels, the only difficulty being the effort to find sufficient fuel and fresh water. If necessary the grey and black tanks of an RV can be dumped anywhere, not just in an authorized drainage facility.

A collapse of this scale will destroy certain concepts of ownership, due to massive property abandonment and the dislocation of the population. There will be a new round of homesteading, recognized primarily by common law instead of government. Those who still maintain ties to the government, such as agents of the Bureau of Land Management or Internal Revenue Service, will find their intrusion to be far less welcome than is currently the case. Conflicts between homesteaders and the military may occur, destroying some communities, but ultimately most areas will be considered beyond the reach of the government.

(CNN) -- As Walter Thomas knows, it's hard to look for a job when your stomach is rumbling.

The 52-year-old from Washington, D.C., started skipping meals in early January when his savings account was running dry and his kitchen cabinets were almost empty.

Thomas at first didn't want to turn to the United States' food safety net, the food stamp program, for help.

But after being laid off in July from what seemed like a steady job in sales at a furniture store, Thomas swallowed his pride and applied for the monthly food aid.

"It lets me think, 'OK, well, tomorrow I'll be able to eat. If nothing else, I'll be able to eat,' " he said.

With the national economy in meltdown, more Americans than ever are relying on the federal aid program to keep from going hungry. In October, more than one in 10 people -- about 31 million -- were using the food stamp program to get by, according to the U.S. Department of Agriculture.

More recent numbers are not available, but advocates for the poor say the number of those in need of aid probably has increased since then.
