I live in the edges of an urban area, literally behind my house is miles of farmland, in front is a metropolitan city. I am good with a bow and arrow (can hit my a target at 100 yards or so), and with a rifle I can shoot a duck out of the air, and hit a deer at 700 yards or so).
Within 1 mile of my house, I have an abundance of the following which can be made into something edible with little/no prep
Nettles, Sorrel, Mushrooms, Apples, Blackberries, Strawberries, Plums, and Cherries
I also grow the following
Potatoes, Carrots, Tomatoes, Chillis, Squash (butternuts and pumpkins), Marrows, Courgettes (Zucchini), Aubergine (Eggplant), Peas, French Beans, Beetroot, Turnip, Lettuce, Cauliflour, Brocolli and in my house I grow a large variety of herbs.
Also within a 2 mile radius, there is a herd of deer (around 40-50 in the herd), of which I would kill 1 every other month. I also have 3 chickens, which give me 6 eggs a week (or thereabouts) and looking at getting a rooster, for the following reason. 1) fertilise the eggs to give me more chickens. When I have more chickens, I'll sell/keep the roosters separate for food. Also, the females will grant me more eggs, so egg production goes up.
I also have a small wind turbine which provides 1kwh of power per day, plus some solar panels which generate 5kwh of power per day. I am reasonably happy with how I am, I grow enough for my family and myself and we can last with the rolling blackouts or what have you (power in our area went out for a week, we were fine, still had TV, internet etc).
