This sounds like a great idea, but people suck. After more than a few people knew about it, the caches would end up being empty because some cheap stoner wanted a smoke and ruin it for everyone else.
I found this forum by Googling "Stoner geocaching". Hahaha. This idea rules. Geocaching on its own is fantastic but making another geocaching network geared to the toking community would be amazing. Lets make it happen!
I have no ability to contribute now but when I do it will have no codeword (well, I will, but it will be expressly abstruse if not already present unless I'm paranoid, then not altered). It will just be there.
