foliage

It's the time of year when folks head towards the mountains to see the fall foliage. Those colorful leaf displays are coming just a little behind schedule.

The fall is a beautiful time of year here on the East Coast, and in North Carolina, we have a resident expert who has long been the go-to scientist for local leaf-peepers: Dr. Howard Neufeld, professor of biological sciences at Appalachian State University. He is learning how and why trees turn color in the fall, as well as why some turn red, while others turn yellow.
