Hi Tom!
Try these links...
http://www.yankeefoliage.com/
AND
http://www.yankeefoliage.com/features/findcolor.php
With the 2nd link, you can click on a particular day and it shows where the colors will be best for that time, seems pretty neat.
We're headed up (I hope) the weekend of the 23rd, should be really pretty up in the mountains, we'll drive up there one day.
Hope your summer was nice!
