Address is wrong, nothing historic is left from this town.
Bridge is actually several miles out of town. Follow signs to it.
Picture is actually Ghost Town of "Buncom." There is nothing in Greenback worth seeing, but nearby Golden is now an Oregon State Park.
Actual location is about 6 miles east of this mark. It is on the east side of I-5 next to the Applegate Museum.
Has been closed for years. The cars are rotting away in a dirty barn and are covered with pigeon droppings. You can peer into a window and see the vehicles
The stories are interesting, but they're just that - stories. While "Crimping" (sailors kidnapped for ships,) actually went on, it was much more open or took place in boarding houses. There is no historical evidence that the Shanghai Tunnels ever existed.
The "tunnels" that did exist - mostly secret passages and hidden rooms in buildings are a decade plus after the crimping business stopped in the 1890's due to the increase in usage of steam ships. Those secret passages led to opium dens and brothels, many of which catered to Chinese people who were hiding away.
