It's great to see you back on the forum! Oct 2-6 should probably be pretty good through just about the entire state I think. The cold air that's coming in tonight is supposed to stay around throughout all of next week and should be kickstarting the leaves that haven't changed yet.
Not sure what areas are "new" for you to explore that you haven't already been but you should take a look at the "Best of Vermont" post near the top of the posts page.
Enjoy your trip and keep us posted please!
