Thanks for the comment. I appreciate it. It was a fun project. No issues with NFZ. I have not attempted this mission since installing a recent Litchi update however, and I read here that one individual had what he suspects to have been an NFZ / Litchi issue that caused his copter to auto land during a mission... Regardless, the actual DJI NFZ around Groton Airport is a less than 2 mile ring. The possibility of penetrating the Class D Airspace around Groton just requires a call for permission.
I grew up in Mystic, and I have seen the town change from a relatively quiet village with practical stores and shops to a bustling tourist mecca of tee-shirts, every flavor of ice cream imaginable, and fancy sweaters for your dog... Real estate is gold in Mystic, and finding a public access spot to fly - without attracting too much attention - is very difficult. That is why I suggest a boat.
