Officials announced in September that the state of New Jersey had purchased 9 miles of abandoned railroad right-of-way to create a biking and pedestrian greenway from Montclair to Jersey City.

One man has been walking the entire stretch and documenting it before it undergoes big changes.

Wheeler Antabanez, whose book and film, "Walking the Old Boonton Line," was released in October, has been recording the grit, grime and beauty that have existed along the railroad tracks for years.

Now his book stands as a snapshot in time just before the line is transformed into something very different - the Essex-Hudson Greenway. The greenway plan is great for New Jersey residents who might one day be able to access a landscape most of us can currently only see from the window of a car.

But it's bittersweet for a man who loves exploring forgotten corners of the state by himself.

On today's "Brian's Positively New Jersey, Brian meets Antabanez atop Snake Hill in Secaucus for a look at the opportunities and challenges the Essex Hudson Greenway plan presents.
