Open to visit in Massachusetts
52 dossiers in Massachusetts carry the open to the public filing — the legend is on record and the door, per the last source, is open. Access is a filing, not a guarantee: hours, tickets and seasonality live with the venue. Everything else in the archive stays documented but admired from the legal distance.
