Spent the majority of time on the ground, have taken a lot of deer, turkeys, elk and small game from the ground.
I also love a tree stand and have used all diffrent kinds for almost 40 years.
Each has its merits and pitfalls. Also different terrains and cover make one or the other better, some areas are just to thick for the ground.
One of my favorite things for decades has been to keep 6-10 tree steps in my pack and still hunt/ scout early season and use my Tree Sling which i wear all the time (as a drag, safety strap, tree stand) if i find a very promising location with a good tree set up I can use it right then or there or set up steps and come back to it later.
I also have a climber which is nice and I use it and some hanging stands. I also like to set up natural blinds, nothing fancy just a spot where my background is good and I can set up or use a couple of dead tree limbs etc.
The other thing i do is where the ghillie leafy type suit which is great.
Mix it up, use whats best for your terrain and how you feel that day.
