Wow. Good question. I think I'd have to go with Trafficante or Los Angeles. Seemed like such a waste. Such good real estate for a family to be in. South Florida and the LA area, respectively. But otherwise for much of the same reasons. They were kinda an oddity in their locales in their heyday. I find small families pretty fascinating.
I like how you think if i didn't know any better i say that you were made guy
