OK, I have the data in JOSM in the WGS84 projection as a GPX file. I 
converted the GPX layer to a data layer. I then zoomed in to one small 
distinct piece and selected all the nodes.

Next I went to the menu and choose Forest and entered a name for this 
piece (Coronado National Forest). However the area wasn't shaded.

Is this the right way to do it?
