People are careless with other people's money. Someone, the state/local government/tax payers, paid for the posts and fencing. Those that are discarding it don't care about waste.Last summer, DH got some 10 foot, U-channel fence posts from where he works. They had built some (Covid related) signs for one of the local hospitals. When the hospital didn't need the signs any more, they said, nah, we don't want the posts. DH asked if I wanted them for garden fence posts. Uh, yeah. That took a millisecond to decide. That was about $1350 in posts! For free!
Well, they have more posts that another customer didn't want. Do we want another two dozen...? Hey, we have some cattle panel we don't need either. Want that?
Pinch me. I must be dreaming.
But I am happy for you!
