Last October I shot this identical shot and the trees were in full color. Not so today when I drove over the mountains in Vermont. I made several stops to stretch my legs but not for photography as I knew I needed to concentrate on my driving. This is the longest leg of my trip. I am in Niagara falls and dang it is raining. I will try to find time in the morning for commenting.
In Australia we usually only get coloured trees that have been planted in towns - it really is something to see whole forests of fall colours in the USA.
Oh I wish I'd known you were going to Niagara- it's not too far from my son's home in Batavia. I hope you have a good trip- and hopefully the rain will stop soon!
