Adray is where my father bought his cameras (the first being a Nikon f if I recall correctly) and still does (Minolta's last DSLR). I bought my Photochems from Camera mart and my Mamya 6mf w/ the 3 lenses. They were at one time slices of heaven for people like us.
How times have changed. I lived in SE Michigan in the mid-sixties and good camera stores were plentiful. Two of my favorites were Detroit Camera and Quarry Photo in Ann Arbor.
Welcome to APUG. If you feel up to it post an introduction here
Detroit Camera (if its the one I'm thinking of) went out of business about 5 years ago. Someone I know picked up a bunch of old old b/w papers went they went out.
