Narrative in Sound & Motion: Choosing a Subject

Gardening is my choice of activity. I keep a small plot and I know a few other people who do it too. I'm not sure if it will totally work because it is coming up to fall but then, there are plenty of things that you do in the garden even when winter is coming. If it should be tied down to a specific action then I could choose the process of growing from seed germination to fruit picking - that could be rendered without having to take live images.
