Hi all
I was just interested to know what are the top 5 things that backpackers never travel without? or just really weird things that turned out to be useful.
Cheers
Top 5 things you never travel without
My dad won't ever travel without dental floss. He's used it to fix more things than I can remember, even using it to tie the chain of his bike together after it had broken.... those stories always cracked me up as a kid! 
I personally cannot travel without music. It`s became boring for me to listen the stupid conversation of other people and etc. Also magazines, regular staff and A lot of money in the pocket :DDD
1 ATM card
1 Credit card
300 US dollars (very important for last minute backup)
2 Universal Plug converter (I always have 1 broken along the way because of voltage)
2 Pens
1 notebook
1 lighter (I don't smoke, but very useful for trekker)
1 small torch light or head lamp (bring along 1 set of new battery)
1 multi purpose knife
2 locks
n plastic or ziplock bags (good for the rainy season)
that is all I can think of.
in places like Thailand, you can find dental floss/shampoo/conditioner/lotion/etc in small traveling size packaging in 7-Eleven and cheaper than home, so no point to bring a lot.
