2. Self sufficiency; town garden, every house with a garden, separate power grid with redundancies built in
3. A park for recreation

6. A 360 shooting range
7. Hunting, fishing store
8. Multiply supply caches staged in woods
9. Early warning systems around the entire town so we can't be raided or surveilled without our knowledge.
