You are hunting for a moving cache. It is a small lock-n-lock container and while it started with a pencil in it you probably want to bring a writing impliment with you when hunting it. Make sure you check the recent logs to know the current status of the cache.
How to move this cache:
1 Find the cache, sign the log book and take the cache with you
2 Post a found it log on the website as soon as you can so other's know not to look for it.
3 Find a new place to hide it, take accurate readings and write them down
4 Post a Moved log for the cache with the new coordinates, the D/T raiting and any hints, stories, or other information you want.
5 Watch the listing for other people to find it and I will update the listing to reflect the new hide location
