Early yet for a lot of screaming. Don't forget your extra early this year. Also, wolves use bugling to locate elk as well. So many have learned to just keep quiet until the rut just drives them over the edge and the urge becomes too great. Unfortunately that probably won't happen until muzzy season We have found wolves to really keep the bugle to a minimum in Idaho. But they will come in alligator style!
What gmu are you hunting? I know a couple people have got some bulls up north but the early archery season has been rough the past couple seasons for bugling... hit and miss.
