I have a different one every week. Right now I'm most interested in Youngstown from the late 1950s, when all the mafia murders started, until 2002, with the defection of Strollo and the conviction of Traficant. Reason being is because it's close to where I'm from, mainly.

My usual favorite is the Capone era though; it's the one I keep going back to after being diverted by the Scarfo era, DeMeo era, etc.

I predict that the "winners" of this thread will end up being a tie between the DeMeo and Scarfo eras, thanks to the excellent books written about them. There are probably all sorts of crazy, fascinating mob stories we don't know much about, simply because a George Anastasia or a Martin Scorsese or someone like that hasn't come along to tell those stories properly in book or movie form. The DeMeo story would be just a boring list of murders if it had been recounted by a hack author.
