Thanks for working on this.  I had a note to fix Regency, and am glad you did.    To figure out if a road is a "real road", which in MA means either a "public way" or a "private way" (easement for the public to pass, but is not necessarily maintained by the government) or something "not a road" such as a driveway, the best resource is "L3 Parcels" or "Tax Parcels" which shows legal roads as carved out spaces.
