As i walked to work this morning i enjoyed the crisp air, the frost on the grass, the sunshine, and the colorful leaves. One tree, that hadn't changed color, was 'dripping' leaves. Awesome. I just stood and watched. But the time clock moves on. I began to wonder: why do some trees turn gorgeous reds and oranges while others just turn brown. Browns are nice, but not especially in leaves. :) There's something 'fun' about walking thru leaves. I wonder what it is? Does anyone know the answer to the leaf color question? Thanks.
