At this time of year, the landscape changes daily; green slowly slips to yellow, red, orange and purple. One of the things I like about walking is that I get to watch the scene unfold each morning. Sometimes the changes are subtle, and sometimes, like after a big wind, they are immediately obvious. Each day the sun comes up a bit later, and I have had to add a layer of clothing. Although I like all the seasons, autumn is the one I greet like an old friend.
