I think a separate regional forum would most likely hardly be used. When looking at the post frequency on the whole board, it doesn't look like a local/regional board would get enough use to warrant its creation. I'd be concerned with a "dead area" of the forum just sitting there.
I do think the idea of meeting other people suffering from the same acquisition syndrome would be fun, so perhaps another way of facilitating that would be good. Maybe a sticky for each region in a related board would work. A person could could create a thread with their state code (like TN, FL, CA, etc.) and see if anyone is interested in meeting up.
