Sorry if i misunderstood, but I have seen it on Youtube too, where they leave a bucket in the hole their digging with a name and date and time, probably while they go have lunch or something, no I agree the person who put the bucket there doesn't either, just like when at Gympie my mate and I leave our digging equipment in the hole we dig, because the creek is about 30-40 mtrs away. I would hope if someone comes along they would realize and have the courtesy to know someone is digging there and there are other spots. Just as next time if they are digging there, I will find another spot. Us old school were brought up in a different era, where a handshake was your word, and there was a lot more respect back then. Hope this makes sense, hard to put into words.
