In this case I think food and water may take precedence.
Besides, I can't play this game. No little paltry 35mm with a roll of film would work in this case.
I would need to carry a big camera, tripod and lens (my Nikkor M 450/9 would work.) A lot of glass plates with a couple of holders. A couple of rolls of good quality paper and all the chemicals I would need to coat my plates and make my own prints. Denise's books and some notes from Jason would be a great help. A nice dark tent to allow me to do everything I needed would be good. I would also need a portable sink and several barrels to fill with water.
In other words...I would need a wagon with a team of horses or oxen to pack everything I would need.
Someone has to be there to record the end of the world!
EDIT - I don't know about this "sky falling" stuff though. That might be a bit hard on the horses!
