The South Carolina Audubon Center at Francis Beidler Forest has a great blog. Changing Seasons is a recent post that tells how weather can affect autumn color.
The fall colors, in my part of Beaufort County, have inspired me this year. I'd say peak color was 2 weeks ago but, there are still some pockets of color that stir my memories of New England autumn days. The ferns have been especially colorful. Almost a burnt orange! I have many pages to journal........ But first, work for hire must be finished :)
