Hello from Massachusetts! In my area in northeast U.S./New England its not at all uncommon to use what we call a "decoy". We also may call them a "red herring" ,"dummy cache".,although "decoy" is most commonly used. I have just under 300 caches hidden with more to come along - to give you an idea on my ratio of hidden caches vs. using "decoys"., i probably have 12 of them. There isn't a set rule to my knowledge of the limit , but i wouldn't abuse it otherwise you'll get feed back in a hurray -- mostly on the negative side. Personally , i think it's a fun idea! Anything to add a little twist for fun! What i have done is sprinkle the usage of decoys throughout my typical area. Some people actually have a traditional cache with several decoys. I have only one cache thats a traditional Easter egg cache ,surrounded by 12 identical color,size easter eggs ,all pink. I only got 1 complaint for it ---most thought the twist was fun. I hope that helps!? QuietBear
