Yeah, or just know a guy.
I have a friend who used to be a lineman for our power cooperative and moved across to the next county. The co-op has a yard where they dump the used poles, free to members. The yard is always empty. Wonder why? Well, my friend knew when replacements were scheduled and would take his diesel pickup, big trailer, and small tractor to work and park it in the yard. If the fellas didn't unload right onto his trailer beside the tractor, he'd do it when he got off work. When he was getting ready to list his property he was cleaning up and I hauled about ten loads of poles out of there and only got about 2/3 of them. Had to cut them 13' or shorter for my little trailer but got to cherry pick the best sections of the diameter I wanted that way. Also hauled a bunch of 8' he cut for fence posts, then helped him burn the scraps and what was left. He had already built a 40x100 stock barn and a much smaller hay barn with used poles, not to mention a bunch of fence posts and got what he needed for his new place before I came along. I felt a little greedy but windfalls like that rarely happen to me and I have made good use of them. Maybe now there are some used poles available there, LOL!
