Mike of the Further In & Higher Up blog has over a hundred posts about National Park Service places. Last month he posted about his experiences in the Blackstone River Valley National Heritage Corridor. It’s a good read I recommend it. He gives the BRVNHC an overall rating of 3 out of five “very interesting”, better than average. I was a little surprised that Slater Mill wasn’t suggested as the place to start a tour when he was at the Roger Williams National Memorial. I suspect if he had visited Slater Mill the “Significance” rating of 2, “debatable that this had to be preserved” might have been higher.
