I've noticed the trees looking distressed for sure. Some, not all of course, lost their vibrant and rich green color like you mentioned. As for the sunset, well, that's always the first thing I notice (unfortunately). The decline into September is inevitable. I always accept it, but must admit, year after year I get that sad/nostalgic feeling that my favorite season is over.
A lot of this hobby is preference; what kinds of things you do and don't enjoy. That's why I've learned to leave good old Anthony alone lol. I still have no tolerance for wrong information (not saying this applies to him), like when people say Summer is nearly half over a week or two after the solstice.
