Again, ONLY if you are ahead of the mob.
What if you and your wife are not colocated at the time of the attack?
What if communication such as cell phones doesn't work?
You BETTER have a plan to meet somewhere.
Either way, chaos eats time.
You'll find that others are also trying to "reach Pa. in thirty minutes". That thirty minutes will quickly become thirty hours.
You will have to abandonn your vehicle, because during such a mass exodus, the roads will be impassable. MILLIONS will be doing just like you.
Then, there you are, with just a B.O.B..
I hope that you have at least two weeks worth of food and water at home.
I hope you have a well stocked and defended destination.
I hope that you have alternate plans for your alternate plans.
IF you can leave before the mass exodus, then do it.
But if there's a chance you'll get swallowed up in the millions of panicked, fellow fleers...
....well, I wouldn't risk MY family.
A sailboat with a good motor, 2 weeks worth of food, and fishing gear is a good idea.
People at sea will be alot more polite than those you'll meet on the road, and at the choke points over the Delaware.
Food for thought.
