Ride between Wiseman's ferry and Mangrove creek dam.

Hey fellow bikers.

I regularly ride from Wisemans ferry and my fav circuit trail includes Simpsons and Donny's tracks. However since I am in training for the Convict 100 and need to do some miles, I plan to extend my ride from the bottom of Donny's track to Mamgrove Creek dam. has anybody ridden all the way up Tenn mile hollow road/upper mangrove creek rd? It seems like there is a track called Blue door point road that joins up with the road leading to the dam.

Any knowledge of rising around the dam will be great.. Thanks
