October 15: 2010 & 2011
Two years, of course, does not a trend make. But it seems to me that in more of the past few years than not, foliage has been duller and later to change than it was the year before. In 2010, though the colors changed later than in 2009, when they did they were full and brilliant. This year, with colder weather finally sweeping in on days of windy rain, many trees have gone directly from green to bare, while others are barely past summer.
