The cache is a small tube, about 4 inches long. It is hidden near an old church.
It does contain a pen, please do not take the pen away, as it is there so people can do something that if they don't do, will deprive them of the smiley. It also contains an assortment of little bits and bobs.
It is very important you replace it EXACTLY AS YOU FOUND IT, so it is out of sight, but don't push it back too far.
If you need extra help, e-mail me via my profile.
The cache is at N50 AB CDE W003 FG HJK
