ok for MY situation im fairly well off.
north central PA being far from most primary nuclear targets though the iron works down the way might get hit with something since they do make parts for things like tanks.
if/when the village water supply gets cut i have a backup well dug(left over from before the water system got out here)
small arms, ammo, and reloading supplies readily at hand zero'd and kept in good maintenance(i'm still working on standardising some of it though)
as for food a decent garden, and my stockpiled canned goods should last quite a while
for electricity my brother and i are building a small windmill to provide some power with solar cells also being put in and a few backup generators to provide power as needed for anything beyond just lights pumps and water heaters)
the biggest concern should a T2K scenario actually occur is building supplies i don't exactly have a conex full of lumber and sandbags ready to go or anything.
but for 90% of any fucked up situation that is likely to occur i can safely say i should be able to last a few weeks of sheltering in place before i need to worry about too much.
