OMG! I'm, like, totally unprepared!!
I have my own shelter, power, water, game, firearms, ammo, foodstuff, paper products,...
...BUT NO BASKETBALL!!
You must tell me, where did you manage to come across such a worthy item? I must obtain one, but I haven't seen one in person in, geez, 30 years.... :)
Basketballs. Hmmm.
A single basketball will stop five of them at once.
But then you have to have outside lights for the half-court.
