With a campside really nearby and watching all the people there trying to put up a tent correctly is always fun ( for us at least 
)
We thought a cache with that in mind is a nice idea..
On GZ you will find some tentrope and a tentpeg. Put the peg into the treestump and at the end of the rope you will find the cache. That simple...
the cache is NOT the box where the tent rope and tent peg is in, you have to search better then that... logpapers in the tent rope box are not valid logs...
Please put away everything as you found it.
Have fun!
