If you ever needed to know why some temperance and prudence are needed when you Freecycle, see the Chicago Tribune story about pet urine and other Items Offered.
After I finished chuckling about the eccentricities the Trib uncovered, I remembered some of the really good experiences I had when Freecycling. For the most part, useful small items were involved. But the best transaction was when a young man showed up and dug out a 6' pine tree to replant in front of his own house. To me, the tree was indeed a weed - a "plant out of place". I was glad to have it gone and he even filled the hole. For him, it was a gorgeous evergreen at a great price.
