The map of the hollis area has several mistakes. I just spend the last 30-40 minutes wandering around Hollis only to find that the names of the streets at the Broad Street(Rte 130)Ash street split is labeled backwards. What is Ash street now should be broad and vice versa. In addition "Camp Union" road is really Depot road. Where did these maps come from, they must be very old (example being the omission of exit 2 on the Everet turnpike) and inaccurate. You should consider redoing the maps of this area.
