I'm almost done adding/correcting all the park roads and trails in Wompatuck State Park, MA, US, based on the large amount of GPS data I collected during the summer of 2008.

Like many other recreational areas, Wompy was split into several pieces from the MassGIS/TIGER import, with the only tags differing being TIGER-related ID numbers and the like. To top it off, all of the common nodes were duplicated or, in some cases, triple. With some JOSM trickery, I fixed all these issues and could also update the park border to its current extent in one of the corners.
