Hi Poid,
I guess the easiest way to take the impotant informations with you is the following (the way I usually collact the data):
When I start off to a caching-tour I take one sheet of paper. I write down the caches in order of planning to log them.
1. Cachename
Coords (N..°..,... ; E...°..,...)
Size
Hint
2. Cachename
...
Sometimes I draw some kind of map which makes it easier to get along with the area. I found out that knowing the size of the cache makes it easier to find it.
