Congratulations to ur friend! Grindstone is a wonderful area and has a unique community steeped in history. My aunt was actually the last school teacher on grindstone- the last one room school house in NY.
I fish around the grindrock a lot. There is a lot of ground to cover. If u follow the fish from the spawning areas in the spring to deeper water as the year progresses….. the patterns r quite predictable. Best of luck and enjoy!!! R u on the front or back side?
