Great photo!!! I've spent many hours on that river! Take a canoe from Medfield or Millis and go down stream some time. It will be an amazing fly along the way! I miss Boston still! Living in the Smoky Mountains of Western North Carolina now. Lots of great photo opportunities here! Google Pickens Nose, Franklin, NC. You'll be at 5300 ft. Class G. 5700 feet is an awesome fly
