Really good topic to discuss! No plan is better then the other. We all have different situations.
I thankfully live in rural county area. Our school is 2 miles from our house. I have been mapping a route through the woods and fields to the school in case the roads are blocked.
I have taught my boys(ages 5,8 and 11) survival skills since they were born. We are also working on our plan for emergencies, we live in a flood prone area. I am using that to prep them for SHTF. :)
I will check back later, good post.
