Surviving 10, 20 or more years after SHTF

[T-oddity]

In some ways John it might be worth looking at some of the Transition movements ideas if you are talking long term survival of communities in that they aim to develop sustainable communities that meet their needs as locally as possible, weather it be locally grown food to small scale local power generation, not exactly prepping for a shtf situation more a cushioning the effects of peak oil, but still some interesting ideas and projects.
