I really don't want to put up any fence since it would serve no purpose other then to cut the wind which isn't always a good thing. Air flow in and around the vineyards is very beneficial. That is why I removed the trees along the road, putting up other trees or physical barriers doesn't really help my long term goal. I will mark the boundry with posts and keep it posted though.
Three strands of barbed wire or field fence won't stop much wind and makes a lot better boundary than a few posts.
