I don’t like to call if I’m going to be moving or stalking. It draws attention to your location. This is especially true if there isn’t much for cover. If I am calling I want the elk to come to me. Go slow and use your cover. I either call or stalk. I don’t try to do both at the same time
My personal opinion If you want to save your season is contact another shop and make the 4 hour drive if they are willing to help you out. If they were a PSE dealer it might make things easier
