"Yesterday morning, I put a set of folding shelves, a stainless steel trash can, and a smaller plastic trash can at the end of our driveway with signs that said, "FREE". I went inside to get more stuff to give away. When I returned 15 minutes later, a woman was hauling the trash cans away on her bike. The shelves were already gone".
