Failure to maintain your geocaches: When you place a geocache, you are agreeing to take responsibility to maintain it. That means that if there is a problem such as needing a new log, leaking container, or missing container, you need to take the time to check on it and repair or replace it if necessary. And if it gets archived, you really need to be sure all of it that is left is removed.
