OK. I was waiting to see if anyone was interested. North America. West of the Great Lakes. North of the Union Pacific Railroad.
I looked last week for a few hours around Minnesota, particularly in the iron range. I came up empty, but I could have missed it.
Hmmm. OK. We'll get really narrowed down. It's between the Cascade Mountain range and The Rocky Mountains.
It's been a while since I've played, but it looks like the CP Yard in Revelstoke, British Columbia, Canada.
