Lol. That and a parking lot full of nuke subs at Portsmouth NH naval shipyard. Too funny to me how people think they might never need to RUN like hell and on short notice.
Morning Mr.Harry
If a possible nuclear event is your main worry then what
gun you pack is of little importance (just run with your
daily carry).
You would probably be way ahead of the crowd to put
the gun purchase money towards a good dirt bike with
a decent sized fuel tank.
You won't be able to out-walk, or out-run-on-foot, a nuclear
disaster so you will need some sort of vehicle. Most likely
the roads will be a stationary parking lot so unless the nuclear
event is very small & very contained an automobile will be of
little use.
With a decent dirt bike (& one for your wife also) you might be
able to find a cross country escape fast enough to evade the
radiation.
If your bug-out bag is going to be set up for living off the land
then some light weigh expandable fishing gear & a Ruger
take-down .22 rifle would cover the food procurement needs.
In an emergency like a sudden nuclear event there is a good
chance that you won't be near, or have time to grab, your bug-
out bag so the gun & ammo that you daily carry will probably
be the only weapon that you escape with.
Now would be the time to figure the normal prevailing wind
direction & plan an escape route that others won't completely
block with cars & trucks. (a narrow nimble vehicle will be your
friend & savior here)
