Letterboxing?

What?

Well, while perusing Lake View Cemetery today I saw something blue peeking out from a pile of rocks at the bottom of a tree stump. I asked Ryan to open this thing up afraid of what would pop out. I figured it was drugs or condoms but then seeing a notebook figured it might be a diary or secret notes (!!!). What it ended up being was a little notebook that had been there for 2 years and was completely filled with stamps and writing from tons of different people. On the inside of the lid it said to go to Letterboxing.org if found accidentally and to please put it back in its original spot. How odd.

Anyways, I don't really know what to think of this. It's quite strange that I saw the box within the tree/rocks to begin with especially after reading the long instructions on how to find this specific box on the website. It's like a little time capsule I found. Worst of all the notebook was full. Should I go put a new one in the box? Am I getting sucked into this weird cult? THIS is the page for the specific letterbox. Maybe I'll "contact the placer." Regardless, I'm off to a hockey game and will have to continue these thoughts later...
