Growing is better than hoarding, because hoards run out eventually, or spoil, or are stolen.
There is no reason to think you must "go back to the land" to grow food, a few acres and a small barn for food, plus a space where you can park a camper and plug in is all you really need. Take your vacations at the right times for planting and harvesting, and do the cleaning and weeding on weekends. If you pick the right spot, you don't have to worry about theft much and not many are stealing raw food anyhow. My family raised huge gardens for years that were as much as a mile from the house, and if we ever had anything stolen, we didn't miss it so it could not have been much. A couple dozen tomatoes aren't missed if you are canning 30 quarts every Friday.
It's work, but retirees need something to structure their lives, and this works as well as anything, and it will cut costs. http://www.landandfarm.com/property/17_ ... ee-429159/
I drop that in as proof that it takes just a few minutes to find fields for sale.
Ok, reason I said "camper", it's not a permanent fixture, thus your taxes do not go up. Also, you can take it with you, so there is no fear of vandalism on something expensive. Tools need to be locked in a SOLID structure that would take considerable work to get into, this especially includes the usual small "cub" type tractors. About tractors, just use a knife to cut a few small nicks in the spark plug wires so you know which one is which, and then reverse them all at the distributor before you leave it. Even if someone does get into your barn, that thing won't start and it takes a good mechanic with a manual time to figure that one out. A hidden valve in the fuel line is good too, thieves don't steal what they think is "junk". Hunter cameras are really good for stopping thieves as well, one fake one in an obvious position means there are others that aren't obvious around the place.
The Barclays fines - hmm, it could be that young investigators are pushing the matter hard. Early millenials are reaching 30ish now. If it makes the boss look good to burn the banks, the banks will be burnt, if it's a GenXer in charge. Or so it would seem to me.
