LOL, well having moved here only 5 years ago from Phoenix, AZ, I don't have the history you do - but I will say that the cardboard I put down to do raised vegetable beds was well on it's way to rotting; I'm sure it's gone by now. In Phoenix, they could have picked it up and reused it as a box after 100 years. You're right, it's the rain - and bugs and worms, I'm sure.
This is a great thread, Neal.
