The hospital was located at the intersection of King and Cannon Streets, and is now the location of a Bank of America branch (formerly C&S). The last time I was there, the "alley" was just a narrow, somewhat cluttered strip of land between the edge of the bank property and the adjoining building to the north. I believe the area where the hospital was located is now the bank's drive-in lanes and parking lot. Sorry, I know of no contemporary pictures of the Hacker's mill/hospital buildings.
