I am going!
It doesn't look like I'll have a job to go to instead so WTF.
I like trains and can't think of a better place to be with a camera or two.
I think I'll go back and forth between Union Station and the engine house across the street from OMSI. Easy to do on the Yellow/Orange line.
Maybe catch OPR at the MAX diamonds (<-- Train talk. Makes me feel ejumicated).
