I mentioned in a comment that weddings of people who lived at Esperanza sometimes took place on the east lawn, up through the 1930’s.  Here is a photograph of the location.  The Norway Spruce framing the picture on the left is gone, taken down about 15 years ago after one too many lightning strikes.  The one on the right still stands, at nearly 110 feet tall.  The lawn has been shrunk, it now stops at the big Norway rather than at the far spruces.  The grove of spruces has shifted a bit as well, the center and right spruces are both gone so the deliberate symmetry no longer exists.
