Yesterday, I discovered one of these with a rubber-ducky pirate attached in Park's End, which was perfect, considering all the ducks I passed hiking in and out! I grabbed three of the many unattached replicas to distribute and also took the duck, mistakenly thinking at the time it was the original. I'll drop him off somewhere soon. I attached a red swashbuckling pirate to one of the tags and dropped it off today in Lafitte's Gold: A Treasure Hunt Adventure! It's a perfect cache to be a part of this challenge! I'll try to get another one of them out to Treasure Island Adventure, also quite appropriate.
I'll be watching for the rest of the crew!
