In the long term, A green house should allow us to grow the varieties of fruits we want to eat...
And in the short term, the tropical fruit availability is only half a state away. We should be able to easily ship in plenty of fresh produce from SoCal.
Finally, I believe that if I were there I would very likely work on an organic farm and maybe even make a living out of it, eventually buying land to build my own farm.
And odds are, if I work for a farm, they will let us live on the land in a tiny house. So organic farming could be a temporary solution until we have bought land even.
These have been a record of my current thoughts. :)
