Re the extra weight. More "mature" hunters here are using Deer towers, these things often have heat and cushioned seats Windows with portholes that open silently. Some even sit on the computer. The first I saw, back in the 1960's was 15 ft off the ground and about 8 x 8ft. Even had a bunk that folded down so the thing doubled as the guys hunting camp. Kerosene heater with coffee pot sitting on it. a swivel chair in the middle and windows all the way round. He even had a transistor radio playing and the deer still walked up the trail every morning and down the trail next to his tower every afternoon. I have seen many since, recently one that had to be 14 x 14 with a cat walk around the outside and a chimney out the top. Heard the guy puts peanut butter on his firewood and the smell draws the deer. That tower must be 20 ft up off the ground out in a 100 acre Christmas tree field. Frankly, If I had such a facility, I would have a second rifle loaded and ready. and a bench shooting table set up with ranges marked along the shooting lanes. I shot one deer offhand in my life. The others were all from a rest, usually a picnic table I moved out into the woods for the purpose.
