I think this is just about the most perfect prompt for this time of year in this part of the world. The fall brings about such beautiful colours as the leaves start to change. Mid-October seems to be the prime time for capturing the best that fall has to offer. If the leaves are turning where you live, grab a photo and show us the beauty in your neck of the woods.
If it's not leaves, find something else that might be turning in your world and capture it.
