These trails that run along Park Presidio are an extension of Golden Gate Park that connects it into the Presidio on the north side of the city without having to walk out on the city streets (although you still have to cross streets between blocks).
It feels kind of surreal to walk along these trails that run along the busy Park Presidio Boulevard that parallels it.
As you walk through here you can see glimpses of the busy traffic on one side and the neighborhood homes on the other between the trees.
Congrats to OwlCacher on FTF.
