Very nice! That sounds like a really cool way of getting the same result I want without having to do much extra work. So, if I understood you correctly you create the mystery cache, which is not logged in geocaching.com. The mystery cache is the prize itself, say, you put some money in it. Then, you take the coordinates of this mystery cache, say it's N x° y.z W a° b.c; and you create 6 other caches. In each one you put the x, the y, the z, the a, the b, and the c. You label them accordingly. Then, you'd ask the finders to find all 6 caches to put the final destination of the big prize. I would actually put a sheet with short instructions in each cache so that it's clear what's going on. I would also add a special sheet with instructions on the final mystery cache with my email so that I can know when they found it (without having to go and check it personally). Cool.

I understand what you're saying but that's not what I was asking. In this case I want to give a special prize to the first one finding the whole series - not just one cache, like the FTF. When I do get the emails, I will not know for sure that they got them all, since, as you say, they could just be marking them as found when not really finding them. So, is there anything that I can add/manage from geocaching.com to provide a safer way for me to know that somebody did find the cache?

I'm just starting to get into geocaching and I'm planning to create a series of caches. I would like to give a prize to the first geocacher who finds all the caches. In order to do this I would need to be able to track who found each cache. I know that people log it, but how can I make sure that they did indeed find each cache? I was thinking of putting a special "code" (or password, say) inside each cache (a different one on each one). Then, I would like the person finding it to log the special "code". This "code" shouldn't be public to the rest of the community, only to me and that way I'll be able to confirm that they did indeed get to the cache. Is there something like this that I can use? One idea that I had was to put my email address in the cache along with the code, and then ask the finder to email me the code. I can then track them on my end. Is there something that geocaching.com can do to help facilitate something like this? Thanks!
