Great lines and reflections.
Good photos! Looks like and erector set, BW!
You had me at bridge. The blocks were originally placed to add weight to the structure and stabilize it in anticipation of the Red River flooding in 2013. Of course, they also keep people off the structure.
I never thought of the blocks being there to add weight. With the "No Trespassing" signs I thought they were primarily there to keep people off the bridge. I have seen vehicles just drive over old bridges once the tracks were removed. Thanks for the info.I kind of "borrowed" the bridge hunting term from you. It is a great term for stuff like this.
