I'm working on seting up a series of 7 caches that tell a story. The first 6 I would like to make traditional as stand alone caches that tell a different part of a the story. The finder can log the cache as you would any other traditional cache. Here is the part I'm not sure about. I want to put an optional twist to this. If the finder so chooses, they write down a code word I will have in each first 6 caches that will be used to find the 7th final Mystery cache. My question is can I keep the first 6 Traditional?

Thank You!!

Every couple days it seems the memory card inside my Garmin 60csx moves out of the slot(a little). It gets annoying to reseat the card everytime I notice the POI section missing. Also I usually have to calibrate the compass because I pulled the battteries. This sounds like a silly question, but can I tape this down (or any other ideas)?
