I have access to un-copyrighted shape files for the National Parks in Alaska and want to add them to OSM. I have read of problems with the plugin for JOSM and wonder if any of you know of a good freeware conversion program that will generate a GPX file that I can then import into JOSM. I'm about to set up a program called DNRGarmin, which will reportedly do the conversion, but will wait for some input here before I proceed. There are many National Parks in what we Alaskans call "the lower 48" already in the OSM database. I'm curious to know how these got there. Thanks Dave
