So this is a time lapse video, that took about 30 minutes to shoot, in a 3-part mini-series, soon to be made into a Hallmark Hall of Fame movie.
Enjoy. I know London did.
Part 1 - Courting the rawhide.
So you see that part of the bone was still remaining. London usually hides it for a later date and then plays hide and seek to find it later.
