My usual travel vest containing:
Cell phone
cell phone AA-battery charger
Nano iPod with built-in FM radio
prescription medicines
heatsheet
deck of cards
paperback book
toilet seat covers
aspirin
gum
toothbrush, toothpaste, dental floss
digital camera
small notepad
pen
business cards

With that stuff I can contact people, be entertained, make friends, stay abreast of news, and wrap myself up. That's good enough for me.
