I have been today taking a ride in a small park along a river and I did not see any colors in the trees only a very very little bit in some trees on the road that lead to the park.
Change of color in the trees!!!
Contrary as to what most of the peoples think, it's not the cold that make the leaves change colors but the diminution of lighting, right now we have lost about 2 hours per day, less sun, less development of chlorophyll in the leaves. less green that let the other color stand out. The only role of cold is pratically stop all action in the leaves and kill them.
