The contents of my backpack

Over the years I discovered the value of a well stocked backpack. I was ready for any situation: stuck with a youth group at a snowed-in airport (games to play), building houses in Mexico (lamb's wool), looking for a lost kid (flashlight), cutting a youth out of a binding piece of rope (knife), on and on.

This is a rather random seeming list of junk, but each item has served a purpose. People of different genders, cultures or geographic areas may want to add other items to the list. Please add your suggestions as comments to this post.

Notebook paper

clothes pin (to clip paper down in a wind)

Various pens, pencils (knife works as a pencil sharpener)

PostIt Notes (many, many purposes)

Chapstick

Multiblade pocket knife (yes, I've lost a couple to the TSA at airports, although I've inadvertently smuggled knives onto an airplane THREE TIMES. Which is kind of scary.)

Small songbook

Pocket package of Kleenex

Pocket package of hand wipes

Markers and, of course, a Sharpie or two

Gum, breath freshener

Eyewash, contact case, wetting solution

An expandable Ethernet cable and USB connector

A covey of Koosh balls

A “spot marker” to use as an indoor frisbee

Miniature deck of cards

band-aids

Ear plugs

Q-tips

matches

Lamb's Wool (to protect against blisters)

Bill sized envelopes

USB flash drive

Aspirin/Tylenol/Advil

I suppose people with more delicate stomachs should carry Tums...

length of string

Masking tape

Ankle wrap

lightweight, throwaway rain coat

small flashlight

Batteries (which has caused my packback to be inspected by the TSA...)

What else should be on this list?
