Here's a house I'd not noticed before. Luckily, the owner was out in her garden so I bravely approached her and asked if the strange tall cones had any particular significance. She laughed and told me they were the "remnants of a broken heart." She went on to say that an ex-lover of hers had dumped them there after they split up, and that she found them very useful for giving directions to her home. Sometimes she tells folks that they are an alien landing strip, or makes up whatever whimsical story she feels like at the time.
