Unkempt cemeteries are a favorite field trip of mine. They were practically in my backyard in Santa Fe and my cousin and I often played in them. One of them is featured in my story, Halloween Blooms.
Evergreen Cemetery in Boyle Heights was founded in Los Angeles in 1877. It's maintained. . . somewhat. It has personality and a certain L.A. charm, derived primarily from the diversity of its occupants.
