Overall route for the drive.
The drive takes us over a mile high up over Mt.Laguna and down into Julian.
Even further down, taking Banner Grade out into the Anza Borrego Desert.
Still lower in elevation until we reach Ocotillo.
Then it's back up the Jacumba Mtns, via Spring Mtn Grade, and a varied return to Pine Valley.
