But isn't finding a Cache also about writing your name onto a sheet of paper? THAT is what makes a Cache a Cache. I'd honesty miss this part of caching
And when I think of TBs how often they are vanishing.. how often is an owner willing to buy a new tag? Muggles are going to take Caches, people will start colletcting these new kind of tags. I myself wouldn't replace a Cache-Tag more than twice.
