Dead falls are all I used for most of my hunting life. Just add a hunting stool and you can be setup quick and ready to go.
A few years back, after being charged by a bear coming to see what my orange hat sticking up was and getting older so looking for comfort, I found a 1.5 wide, 18' high treestand on sale and been hunting in comfort since. I added a nice padded seat cushion, cup holder, rifle rack, heated vest and tree umbrella for those drizzly days. The other hunters call it my Barco lounger. I can truly enjoy the woods in comfort now.
The tree umbrella really did it's job a month ago during the the early season senior hunt.
I've gotten a deer every year since I've had the treestand.
