The Highest I have climbed in a tree was about 35 feet. I usually dont like going that high but I had to because there was a clear cut right next to a food plot with pines about 15 foot tall all around the plot. In my old club we were aloud to cut down pines but this one they would kick you out if you even put spikes on pines. I also figured being so high up there was no way a deer could see me but I was wrong, the doe spotted me (i guess because i stuck out like a tird in a pounch bowl)It was a great hunt though, took a big doe.
