Wow - it looks like we could you a forum just for this question *haha*
Thank you so much. I was afraid of over-packing, but also of under-packing.
One thing I picked from a survival guide was (seriously) something which has no weight really, but can be used to transport water - a condom!
First I giggled, but actually if you are in an emergency situation that is not a bad idea actually. Unused of course.
I am compiling a list of essentials using your suggestions, I got a Swiss Army Knife, the big one - love it!
Bandages and bandaids are a no-brainer, I did not think of a small mirror! Makes sense if you have an injury to your eyes or so.
Ok, sitting down now and going through everything to make sure I will only take what makes sense...
Thank you again! :-)
