Barn appears to have been located approximately where the parking lot of "Central Christian Church" (as labeled on current map) now sits, based on an overhead image from 1937. The most recent satellite image indicates that the house in the photo is still there, although it is now only accessible via Whilden Court, to the north, as opposed to Hwy 14 as shown in the photo.
