If you want to know why I smoke up, you should have seen what just went down in my backyard. I started a big old fire at 5. There's still flames leaping around on it right now. We ordered pizza and when I went out the back door to meet the delivery guy, 6 deer took off from the feeder with 4 of them stopping close enough to the fire to feel the heat. I could smell the smoke at the house 100 yards away. They all had to walk through the smoke to get to the feeder. More proof it's a smell that doesn't phase them.
