Elizabeth Fink has been using the new composting toilets near the Wissahickon Environmental Center (formerly Andorra Tree House) at the northwestern edge of Fairmount Park, Philadelphia. It never smells, she says and there's Purell for hand sanitizing. She thinks it's a big improvement over the old "Johnn(ies) on the Spot". She's careful that her cell phone is in a zipped pocket, however, lest it inadvertently fall into the pit! She and a companion had been taking a walk in the woods and recommended I check out the toads mating in the pond above the tree house. Watch video here.
