I have a pretty steady supply of used pallets at work. I've been carrying them out to the farm and waiting to use them for stuff. I have a ton of old t-posts out there already, and I realized I could just slip the pallets over t-posts to make a
fence. I bolted some like-sized pallets together into roughly 8' sections, so I don't have to use quite as many posts to hold them in place. The nice thing about it is that once the pallets get too worn or rotten or suspect in any way, I can just re-purpose them elsewhere on the farm and slip a new one in their place as I go. That
should give me some protection against feral pigs coming through as well, I think.
