The images from the shorpy web site continue to amaze me, every day. Never miss it. Anyway, a posting today shows the Cadillac Motor Car Company in 1909. The only clue to the location is on the side of the railroad shed, with the last two letters of a street: "----rd Ave." The railroad tracks would make me think the southwest side south of Fort Street, but I can't think of any street in that area that ends in "rd".

Take a look and give me your best shot! http://www.shorpy.com/node/8979?size=_original
