I can't imagine any LCN family trying to come down and take from Philly. It's not like Philly has every book and shy under their protection/control. There are more independents than connected players.

Philly doesn't control construction or trash or any other traditional mob racket. they have some gambling. Unless the Genovese had some "world domination" plot for Delaware Valley, murdering a few people for a few hundred thousand and a ton of exposure just aint worth it.
