I'd say the foliage is currently at about peak color at Grafton Lakes State Park. The day started with dense fog, which partially burned off to allow some sun toward the end of my visit. 

I ended up using only the 14-35mm lens and ended up with 50 images to add to the Grafton gallery at https://trulandphotography.com/grafton. Here are four samples each from Long Pond and Mill Pond.
