Cincinnati or Cincinati?
Lotsa tunnels round these parts. Still a bustling biz with barges on the Ohio River- once known as Porkopolis.
Could it be part of the underground railroad, post-slavery, but for other goods?
Cincinnati Union Terminal- where all recruits departed from on the their way to WWII from the mid-west. Railroad central (with creepy architecture and symbolism times 10).
Just north of Cincy is Circleville, OH. Once the end of the underground railroad and chalk-full of tunnels. Circleville might be THE opioid capitol of Ohio. Drug smuggling?
