This week, I'm adding a number trails, waypoints, and other points of interest in and around Acadia National Park in Maine. I've been using the MapZen application, mostly for quickly collecting waypoints of commercial establishments and using the Garmin GPS Map 60CXS for collecting the tracks of trails, and more remote waypoints. Most of this area was part of the original TIGER import, so I've been correcting the alignment of many linear features and bringing the road names into agreement with the OSM model.
One quick update: many of the carriage roads in Acadia National Park, and (astonishingly) some of the hiking trails, were originally part of the TIGER import. While I have updated the alignment and corrected the topology and connectivity of these features, I have kept the original TIGER tags, but changed the tag TIGER_reviewed=yes.
