Here's a few additional items I have put in my caches:
- Small packets of sugar, salt & pepper you get at fast food chains. Put them in double ziplock bag
- Other items from fast food chains ( like paper towels and plastic spoons/knives ..etc)
- A cheap can/bottle opener
- Few pencils and crayons my kids have wasted
- Newspaper ( to sit on, or start a fire, whatever. You can even make it in a cone shape and use as a loudspeaker)
