I'm a fan of diversified investment - I own a small condo a block from the largest freshwater body of water, in a city in the heart of food-growing country with cold winters (global warming would likely extend growing season as Kentucky et al fry), and Chicago is the major rail transit hub in the midwest.
I don't own a car, but I have a girlfriend with one who also has an 80 acre farm in her family, and I'm about 2 hr drive from my brother with 150 head of cattle and a cheese making dairy farm.
I think that I probably need a sailboat, a container garden, and a motorcycle to expand my "world goes to hell" flexibility, but moving in the right direction. I have my captains license, but really ought to learn to ride a motorcycle I suppose...
EDIT: reading that, it sounds a bit like bragging, but it's partly tongue-in-cheek, though they are all thoughts and discussions that I've had. I agree with the above that urban growth is likely to continue, and I suspect that the hard time new grads are having now is going to exacerbate that trend as they get into scarcity habits and pursue network efficiencies for work and living. Rural land can support you, but it's HARD to produce savings, cash or work-free production there.
