Answer: You have my sympathy! In my experience, too, the only reliable solution is a tall fence. I have seen some made of a suitably rustic (eg split rail or three board or picket) wooden construction on the lower three or four feet, then topped by several simple strands of wire rising to about eight feet (or more) supported by occasional taller posts. In other areas I have seen fences of simple strands of wire stretched from posts; these are nearly invisible except for the posts. (The least expensive and easiest fence to install is simply metal "T" stakes pounded into the ground and electric fence wire strung from post to post but not electrified.) Some gardeners are able to conceal black netting fencing by installing it at the edge of the woods. These are all fairly unobtrusive compared to stockade fence and the like. Unpainted "weathered" wood tends to fade into the background better than painted wood, and surrounding greenery tends to obscure most posts and fence lines to some extent. Unfortunately I don't have a specific book to suggest, but nearly any garden magazine or book has fencing in the background of many of the photos. Good luck with your fence!
