My pasture is in serious need of re-fencing. Most of the wood fence posts are either rotten or burned (from burning ditches), and most of the metal T-posts are rusted and coming out of the ground. The fence isn't in much better condition. It's so rusted that, in some places, the wires are totally rusted through. What would you recommend I use to replace the fence? Please keep in mind that I don't have the funds to go über expensive.
