Denver 30: 13
Technically not in Denver, but one of the adjoining burbs — this building is within a large cemetery. It is a beautiful, 200-plus acre space, with giant ancient trees and memorials that vary from ornate to bizarre. There are soldiers from the Spanish American war buried here, to give you an idea of how big those trees really are.
Perhaps the scariest aspect are the coyotes that live on the property. They are the size of golden retrievers and I’m convinced are looking for a Willie Nelson Mandela sandwich. Coincidentally, over my dead body.
