Years ago, when we gun hunter my Uncles mountain in Schoharie Co. NY...
At the top of the mountain, was a HUGE boulder, split in half thousands of years before. It was now about 4'-5' between the 2 halfs. It was called "Split Rock". It was a natural ground blind,with deer trails all around it. My Uncle always said "If a man sits here all day, he WILL kill a deer!!!" Those words came true MANY times, over the years...
My Dad would sit on the mountainside in the "Flat Woods" below in the morning, then head up to "split Rock" about 11am for lunch. Once he got there..... He built a fire. We had a Basket Grill that hung on a nail year round. Lunch was Hot Dogs, cooked over the coals. Over the years, many including myself, killed deer there. While the fire was smoking away..... Off the top of my head, I can remember 19.
Fire & wood smoke, are natural... Give it a try!!!
