I once got some used wood for free from Craigslist…somebody gave away his fathers old scraps.
One piece was a 2x4 from 1982, from RONA (a Canadian store) and it a very beautiful piece of pine. It was exactly 2” by 4”, and straight grain. Obviously it was air-dried by then :)
Now it might have been from the select pine section of the store, not SPF construction lumber.
Pine ought to be treasured, not tested as a garbage wood like we do nowadays. If it were scarce it would be priceless.
