An excellent article. I saved it for future reference.
I don't believe I can save enough for a down payment on a house now (I'm getting long in the tooth) but saving for some land might still be doable. I was thinking maybe being able to get some acreage and use it to grow on as well as camp at. Would also serve as a place to get away from the city if/when things get chaotic.
The compost idea would be ideal for such a vision. The only thing I wonder is for a coffee alternative as if things go south coffee will not be easily obtainable, if at all.
