I have found that an eight foot fixed knot fence has done the trick for me. It keeps the elk out, hunters out, cows and dogs in. It can take a 1500 lb hit and isn't easy to climb. It definitely says stay out! I put up no trespass signs and signs about a bull trampling you in 3.2 sec and people are afraid of bulls. The fixed knot fence looks good too and way cheaper than chain link.
