I would say that you can always ask the host. Some events have “Human caches” where you have to ask everyone if they are a cache, and if so, you sign their log book. This is a great way to just get around and meet people outside of your circle. Also, there is often a cache that is not mentioned. People just “hear” about it, or stumble on it. Keep your eyes out. If you see people all huddling around something, or picking something up, they might be looking for co-ordinates to a bonus cache. See you in June!
