It was real foggy early that morning and could not see very much. I had a doe start blowing up on a ridge. I picked up my grunt and grunted a few times to see if she would stop blowing. She stopped blowing and he showed up on a ridge about 200 yards away about 5 minutes after I had grunted. I realized through the fog that it was the buck I had been hunting I shot and dropped him in his tracks.
