Your local lumberyard might post photos of all that "as is" and "bring hammer, come get some" for their regular customers, as sometimes a custom homeowner will ask for cabinets, built-beams, etc. for that look, if not architects that have reclaimed old bridges, etc. for the rustic beams.
You could just sit and check them out with cash & carry.
NextDoor.com is in your area & posts photos for you - has well served Aggieland in such items, less so has Facebook Marketplace. Reclaimed Lumber is not in your area but maybe a lumber wholeseller might be worth a call.
Long shots include donations (they come & take down what they need) to
Habitat for Humanity
Goodwill shops willing to come & get it (rare)
High School wood shops

Hoping Socialism Sucks gets it all but that means You taking it all down, dealing with the nails, shipping, etc.
I'll repost this for you on my facebook website ....
