The Presidio Pet Cemetery in located in the Presidio of San Francisco.

This pet cemetery, wedged beneath an overpass, is a secret garden, unkempt and overgrown. The grave markers range from whitewashed and stenciled boards to elaborate marble edifices. Most have assumed wild angles over the course of time. All provide vignettes of cherished companions, be they birds or bassets. (My favorite is "To my beloved rat Spike who made my life so much better," penned in a child's looping scrawl.)
