The trail IS there, but not officially open. I walked it back in July. After a mile or two of the weeds, the trail that we all know and love resumes all the way to Black Walnut and on to Machens. There are no services available, at least when I was on it. The Machens trailhead is a little difficult to get to, but that part of the trail can be done.
