After spending time surviving the apocalypse in order to try to bring back a little bit of the past, it would be nice to include commemorative items in boxes, lockers, etc. It would be cool to be able to celebrate Christmas by finding loots, like an artificial Christmas tree to assemble, or at Christmas time allow you to cut down a pine tree and turn it into a tree, ornament lights, reindeer, sleighs, etc. And at the time of Halloween find decorations, costumes and on Fourth of July and New Year to be able to set off some fireworks, of course the sound will attract unwanted guests.
