AZGARY, All three of those stores were in that shopping center! I too remember the Ford Rotunda, and remember when it burned down, as I also missed going there with our family. The Henry Ford museum and Greenfield Village were always special places to visit. Fortunately the latter two are still there, and, nicely renovated. Bushes and Piedmont Jewelry sound like great memories.
There was a hardware stor, Bidigare Hardware, on Kelly, north of 7 Mile Road that carried Lionel trains. The year after I received my Super "O" set for Christmas, my dad went to the hardware store, and the store was getting out of the Lionel business. My father bought a number of sections of Super "O" and a ZW at the final closeout. That was a huge boost to the size of my layout.
