I too have noticed the odd early changer.

In some class (I think it was CT Nurserymans training years ago) we
learned plants' annual hibernation cycle primarily reacts to the
shortening length of day following the summer solstice. As my fading
memory banks recall, the physical changes start occurring about a week
after the solstice, becoming more and more noticeable as time marches
on.

Any BIO people care to comment?

Sadly/happily I will not be in VT this winter to enjoy the narrow
winding trails and hardwood forests. But I will hopefully make do with
mountains out west. Last time I was out there was Utah in 2006; it was
a pre-tele and pre-xcd experience. So, it will be a new adventure :)
