My answer:
1. Buy all of the NATO style weapons you can afford to buy along with atleast 1000 rounds of ammo for each. Do so with no paper work at gun shows or from people in the newspaper.
2. Plant them (yes in the ground) spread in all four compass points from your house within 10 miles to make it easy to walk to.
3. Formulate a bug out plan with your family.
4. Learn to be alert - they will come at some point.
5. Try to find and develop a hide away for your close relations.
Oh yea and for all of you who think I am paraniod, Look at the fine job your government is doing to protect you so far!
If it's time to bury them, it's time to dig them up.
