Here is the new TAG. Duck is at the base of the large tree to the right of my bike.
Close up of duck location; stick arrow points to the location.
And here are the clues:
1) New tag is exactly 6.6 miles north/northwest of the previous tag (as the crow flies).
2) The picture below should give you all the clues you need for the location: (if you can read the big sign in the picture)
But just in case you need more, tag is still located in Madison county, and at the end of a road who's name is the opposite of "STRONG SOLID".
