So the Ducks Unlimited folks came out yesterday afternoon. I had not discussed allowing folks on the farm with them in over a decade.
Things have changed...I am working through the legal and financial issues today and will discuss with my wife and son when they get here Friday. Still don't know if it will be worth the effort.
Here is a picture of the location they are interested in, taken when they were here. The Duck blind used to be to the left of the tree with the Osprey on top

The inflatable tent idea is perfect for what their "clients" want, at least according to the DU guys.
The below is a top down look at the location. The tent(s) would be set up to the right of the white square along the marsh. The edge of the marsh is drive-able.
Sorry for the long post, it is just interesting where this place can lead you at times.
