bought a decent size pop up ground blind and i dont have to sit still.
I move around a bit and even stand up occasionally to stretch the legs. Use a pretty comfy chair too. I've actually stayed in it from 5AM to 7PM once

The best test i had was turkey hunting this spring. Has some turkeys near by and my bussy and i were in the blind. We were moving pretty good inside the blind while they were near us but they never saw us
