Thanks! Yeah it's a wonderful place for sure. The area we spend a lot of time in has a lot of Native American names to it. Pemigawasset, Piscataqua, Androscoggin are some of the names of the rivers around and it's nice to see them get some recognition for their ingenious ways and adaptation of their way of life to the region for so long.
It's clean and people do swim in it yeah. I think it's likely because the rivers here freeze during the winter so the water is incredibly cold except for maybe 45 days in the summer, where it's not too cold to fend off the heat that we get exposed to. We haven't swam in the river yet but maybe one day!
