The cache is a very strong waterproof plastic bag that contains just a logbook
and a pen. It will last several years.
You will have to leave a marked trail to reach the cache.
The terrain is easy: my 2 daughters (aged 8 & 10) helped me to hide it,
but we didn't walk all the way from the car. We used a rowing boat on a lake .
The cache is under a big stone.
