Whenever I hear someone say "the horizon" I immediately think about actually going to it. Not in a sense that the horizon is actually what it is (e.g. a field or ocean etc.) but more that it is a place which is mystical and magical. Its like the 'end of the rainbow', somewhere where you want to go and you dream about, but yet it is pretty much impossible going to 'that' idea of the place. In reality the end of the rainbow could just be a bit of road, a roof or anything in that matter. Thinking about what the Horizon would be imagined to be like would probably be known as a big, blank piece of canvas/room/place that displays whatever landscape or object that the imaginer/visitor wanted. For me it would be a wide field, that had daisy's and other wildflowers growing in the tall long grass. It would be a place where no human had ever polluted or destroyed it. It would be a zen place, a place to re-gather thoughts, a place to imagine things and to create ideas. For me the Horizon would be another perfect thing to add to our world.
