I like your stands you build. We build stands that are similar but we put them 4-10 feet up on 4x4 posts sunk in concrete. Haven't had one stolen yet but hurricane Michael tipped one over. LOL Our stands are 4'x4' and there is 7ft of standing room inside. We paint the insides with flat black paint and you'd be surprised how it's almost impossible to see someone inside of one. We also have wooden, hinged at the top, plywood "windows" we can close to make it darker or open for ventilation. Our shooting benches are very stable and are similar to benches at a rifle range. We also have shelves above them for "stuff" hunters always have with them. One of the things I INSIST on is a wooden ladder at a comfortable angle for entry and exit. If you stand up with your toes touching a ladder and extend one of your arms out your fingers should barely be able to touch the ladder as it leans away from you. That's the perfect angle. You can go up and down these ladders carrying equipment with ease and step right into the stand without that crazy angle and dangerous part at the top where you transition from your horizontal flat floor to a vertical ladder. That is incredibly dangerous especially in the dark when you're stressed and/or tired. Our ladders are made of 2x6 boards with 2x4 steps that are 12" from the top of one step to the next. It's amazing how easy and safe these ladders are to use. A fireman taught me this trick. In Florida it's a 3rd degree felony to trespass with a firearm and we post our properties well. There is still some theft but it's not too bad. I always wished I could post a sign saying "Trespassers will be shot and survivors will be shot again" but I've always worried that if someone ever DID come up shot for some reason, my signs could get me in deep doo doo and would be used as evidence of "intent" against me.
