Thats the spot! Thats where I would sit. This arial photo thing I have been using the last couple of years to locate such funnels and areas like this in my hunting zones. It has given me some up my most productive spots ever, especially during the rut when the big boys come out of hiding and are moving. What state are located in, do you have a good amount of big deer in your area?

Oh depending on what it looks like inside the woods I would maybe even put two setups in there for a westerly wind and some kind of easterly wind. Make sure they both work though if the wind is coming out of the north for that is when deer will move the most, with that cool air. Let me know how it worked for you. Looks sweat.
