This thread has evolved but the discussion is well centered.
The original challenge is how fast can you and your gear make it out the door. This challenge remains. 1 minute was the time quoted for the minuteman militia of the revolutionary war. It is not about moving stealthily. It is about moving period. We all have to remember that in order to survive sometimes we have to give up stealth for speed. Other times we need to invoke full stealth and say to hell with fast.
Here is something for the scenario..if all hell has broken loose the best thing you can do is move with confidence. Your neighbors may have lost all ability to reason due to panic. It is nice to know if your abilities match your intentions.
The more you sweat now the less you bleed in a SHTF scenario!!!!
