Does anyone else feel that there is some kind of inborn skill required for this?
Now, I think that I'm getting pretty good at it, but really, how do you do it? Sometimes, it's like there's a magical perfect solution to the puzzle that you have to get JUST right, or forget it, you're there for ten minutes! Or, it's like opening one of those joke peanut brittle containers with a exploding snakes in it. Now I've got a lap full of stuff, and a muggle's on the way!
I realize that I'm pretty new at this, but out of curiousity, what's the intended end result of the calling cards? Is the cache owner supposed to take them out after a while, or are they supposed to be a permanent record of who's been there? And if so, what's the log book for?
