the rednecks live closer to the posts than you do. at this point they probably see it as a game and are excited to see your next move. already one of them has predicted your quickrete move, and are considering bringing in a tractor to pull them out. another redneck thinks that's too much work and wants to just cut them off at ground level with a saw, but the first redneck is a stubborn craftsman who believes in seeing a job out to its end.
you're trying to solve a social obstacle with technology, and you're up against rednecks. technology doesn't really work on rednecks.
have you tried talking to them?
