Last year I saw the darndest thing. It was about lunch time, and I was getting ready to go back to the cabin. All the sudden, a spike appears in the field. I watch him for a bit, then as he was walking away(200 yards, or so), I decided to grunt at him. He turned around and came 100 yards closer. I got quiet and he walked away again. I grunted and he came back again. This went on for 15 minutes, then I started "playing" Happy Birthday, on my grunt tube. That spike took off and didn't look back!
Then over the rise in the field, came two bucks! A 7 and an eight point. All this while blowing like mad on my True Talker. The 7 had quite a lump, so I let the 7mm SAUM sing, and had my deer.
Do grunt tubes work? I've had mixed results over the last 15 years or so. But some ridiculous calling brought three bucks to me in the middle of the day on Nov 20!
