I'd say that's true in most of Florida. At least outside of cave country. When I get my tanks filled locally, mine are usually the only DIN tanks in the bunch. Same for when I go to the Keys. At least all the shops can fill either.The dive shops I visit in South Florida are pretty much devoid of BP/Ws and DIN.
But, that reminded me last year I took Stress & Rescue with two of my regular dive buddies. One uses yoke, the other and I use DIN. In addition to the students, there was the owner/instructor and another instructor. They both preferred DIN. When the owner was getting tanks ready for our dives, He grabbed all the DIN tanks they have in the rental group. Turns out that's 6. Owner grabbed two, and saved 4 for my buddy and me. The other instructor had to use yoke with an adapter, and was not happy. Probably the first time that happened.
