1st

First up are these lovely glasses. Now these are not just great sunglasses but they are also spy glasses! When looking to the corner of them you are able to see what is behind you. So not only will you look overly cool and totally 80's(har har) but you will be able to watch for watchers or see if people are following you.
2nd

A flashlight that can be winded up. No need for batts and great fun to wind up!
3rd

You will need a wig! Great for disguising yourself..you can ever use the glasses!No one will ever know its you.

4th and last

A note book and something to write with. Great for keeping notes and when bored you can play tic tac toe.
Now this is all I can come up with now but I am sure others will be able to think of some clever stuff..
Of course it is always wise to have a first aid kit and some extra toilet paper..just to be safe. I don't always trust washroom stops to have toilet paper.
Hopefully this will be helpful.
Good love Bree,Daniel and Jonas! Don't forget I've got your back.
