We keep a lot of dried beans and rice, so I could last a bit longer than 3 days. Assuming the asteroid doesn’t affect the power grid and prevent me from cooking them. It wouldn’t do that, would it?🙁
I have some briquettes and lighter fluid. I think I need some firewood. A lot of it. And some more bottled water. And a storm shelter. And lots of those ketchup packets.
But I imagine that there are still lots of underground bunkers from the days of the cold War, filled with water, dried beef, vitamins and information and gizmos like iPhone helicopters and guns, and the select few who get to go in will emerge from the wreckage and be able to tell our story.
Only problem is they may have to stay down there for 10,000 years.
