brian b: Since my suggested parking has a No Trespassing sign located at the entrance to the railbed (although I am not certain who has the authority to shut this down, as 2 Mill Street most certainly does not), I have removed this cache. Here is a link to what the "Dirty Little Secret" is all about -- a Level 2 Hazardous Waste Site. This mill used to make carpets, and one could tell the color of the carpets by the color of the Moodna.
