My partner and I hunted the GPNF opening week. Found more bull sign than we could shake a stick at. Single bull staying hunkered down all day. Too hot that opening week. We would find new scrapes from the night before. We even found urine still soaking into the trail one morning. The only bugle we heard all week was another hunter. Not real good bugling and he almost swallowed his cow call. But it was still a great time.
