An old picture of the R2 Clay Mine "Dinky" Tunnel near Smokey Valley Truck Stop.
I'm not for sure where its at though. They tell me its through the "cut through" down Rt 2 which is from the entrance of Blueberry Ridge ,
before you get to I-64. They say this tunnel is on the right and you can still see the indenture on the hillside.
I think it might be between Citgo and Twlight Drive.
