I've never understood why we should be so stealthy with a raised box blind entry. I don't have the ladder to any ladder stands concealed, and some of those in the woods.
My goal is to never let the deer know when I come into their area nor when I leave. I'm sure I've not succeeded all the time but if the wind is right and I can get up and down without them seeing me I have a good chance of getting out without cluing them in. I have most of my blind's entrance and exit paths blocked as far as sight goes. If I take care of the scent part as good as I can and I hunt the wind I don't bugger up a blind for hunting again in the near future for the deer I want to shoot. Young adult deer aren't
much of a worry to blow up but older ones are an entirely different story.
I'm blessed in that the vast majority of my blinds have been able to be developed into low pressure entrance and exit opportunities.
