Bowhunting from the ground is tough.Pretty sure way more people fall from stands and die/gravely injured than are shot through carelessness and accidentally but that’s not the point of the post. I thought you had to be in a tree too but started hunting from the ground in 2001, now my bow success greatly diminished but had I been rifle hunting I would’ve had quite a wall full of antler! Also have less areas to see from many ground set ups but I’ve enjoyed it. Unlike you though, I seem to carry more food, coffee, sometimes a blanket and my pack weighs maybe 25lb early in year to near 40 later.
I try to focus on spots where the deer will be somewhat focused on where they’re placing their feet, such as a creek crossing, gulley, etc.
Next time you watch one cross a terrain feature like that pay attention to where they fix their gaze.
