About September 1st, put a ground blind on one of the plots where you have knowledge of deer entry from past experience. Needs to be there all the time, just like a traditional wooden house. You will sacrifice a few things; the blind will weather, you will spook more deer, and that will compromise your long range hunting. But it's probably the best option. Other than the double ladder idea.

I do not hunt the plots, but that is due to the constant pressure from guns. I will hunt them early season, and would hunt them more if I could control the hunting pressure. If you control the pressure, you have more options.
