To ensure the correct movement of trackable items.
And to assist in managing this b&b it would be good when claiming a find on this cache if you could;
1) Find the cache,
2) Count the number of trackable items in the cache.
3) Swap an equal number of trackable items in and out of the cache, ensuring that the number of trackable numbers is the same on leaving as when you arrived. It can be any number in total that are moved as long as it the same number in and out.
4) The movement of trackables via the internet must happen when you record the find or write note.
Multiple visitatations to the cache are allowed, but only 1 find can be recorded. All other visits should be recorded as a write note.
