Perhaps I should explain in a little more detail.

i) Lock Down was a euphemism for Martial Law. Even Journalists from News and paper media were threatened by Internal Paramilitaries and Police tactical units at Gun Point together with the arrest of civilians who ventured out in various neighborhoods during the 'Lock Down'. There was also the searches of private residences.

ii) The Boston Marathon terror attacks photos showed Special Forces soldiers carrying Geiger counters just after the bombs went off. There is speculation that they were Weapons of Mass Destruction specialists together with other black Ops.

iii) The recent North Korea situation raised US war preparation recently to DEFCON 3.

iv) Chechen Terrorists and WMDs. When reality gets to point that it looks like a Team America script, its time to Bug Out

My main point was really the difficulty of Bugging Out whether the destination was in an aurban or wilderness area during a Martial law situation.
