If your parents need the money for retirement anytime soon, perhaps they should just sell it right now. But in the long run that city will keep growing outward and the land will appreciate. Perhaps not over the course of the next 3 years, but long-term the prospects should be great. But holding it long term wont help your parents take that vacation next year or enjoy their retirement. Maybe they sell 80 acres and pass the other 100 to you, I don’t know. If they want to pass it all to you, then I suggest that you immediately:
-Cover the perimeter with barbed wire, and to the south fortify it with razor wire.
-Establish a defensive position along the most likely avenue of approach to the south, and set up foxholes approximately 15 feet apart.
-Stock pile weapons, food, extra ammo and fuel and see if you can get your hands on some night vision goggles. Buy five pairs, and don’t forget the cold weather gear to include cross country skis.
-Weekly, reherse leaving your day job in the city on moments notice. Maneuver through corn fields if you must, but make sure to use a different route each time.
-Buy a rugged laptop with a wireless data card and monitor piggington.com 24/7. When news breaks that the housing bubble has burst in Minnesota and the nation has fallen into a depression you’ll have nothing to worry about.
