The Bay Area Ridge Trail winds through the southern part of the Presidio, a national park within the boundaries of San Francisco. This part is referred to as the Southern Wilds because it is forested, while other parts of the park are landscaped for other uses.
This walk in the Presidio is a small part of the overall Bay Area Ridge Trail. When completed it will allow adventurous hikers to circle the Bay Area using over 400 miles of trails, mostly on ridges that afford a view.
The fourth Nicole Tang Noonan mystery, tentatively entitled Dark Video, opens with a scene on the section of the trail pictured here. Nicole follows a section of the trail for pedestrians only into a densely wooded section where something unpleasant happens.
I am currently writing Dark Video and hope to publish it this summer.
