Thanks for talking yesterday regarding the neighbors on Bog Meadow and your concerns since you want
to develop land there yourself.
However, you have valuable information about the two aquifers on the land. If you would be willing to
submit a SS Planning Board Project public comment regarding your research on water, it would be much
appreciated.
