I went to Batsto yesterday, and the hurricane a few months apparently flooded some of the ground and washed up old glass from the glass factory that once stood on the site there. Between the old sawmill building and where the factory once stood is where to look for the glass. Little pieces are all over. I took a couple and one of the park employees was actually encouraging people to take some of the glass. Production of the glass stopped in 1867 so you know the glass is pretty old, which makes it fun to collect.
