This started kit is what I've been telling my non-prepper friends to have and some of them are starting to come-around.
Gotta love Craigslist and yard sales. My wife got two Coleman catalytic heaters for a buck a piece a while back from an older lady whose husband passed away. I've found too many deals to list here.
Good list, I would add a few jars of peanut butter and hard tack too. Gives you the carbs man
for defence prolly good to have a baseball bat if the apartment is not gun friendly.
Heavy curtains or black out blinds are a good idea for light discipline, no need advertising you still have hot food.
non semper erit aestas
It will not always be summer
