Interesting. The pin-pen merger and caught-cot merger have very little (if any) overlap. It looks like Florida and Texas might soon merge caught and cot, while retaining the pin-pen merger, in which case they'd only have 13 vowels, but I suspect they would probably end up splitting pin and pen eventually as their regional accent gets watered down to be closer to the General American accent. https://upload.wikimedia.org/wikipedia/commons/1/12/Pin-pen.svg https://upload.wikimedia.org/wikipedia/commons/1/12/Pin-pen.... https://upload.wikimedia.org/wikipedia/commons/thumb/0/0a/Cot-caught_merger.png/1024px-Cot-caught_merger.png https://upload.wikimedia.org/wikipedia/commons/thumb/0/0a/Co...
