Added about 18 km of roads, after managing at last to pair an old bluetooth GPS with my mobile phone with TrailExplorer, I can stuff the gps into a saddle bag, phone in pocket and drive around Paris...
Not too many problems with JOSM - generally painless, but some problems in finding out how to colour a road (that's ok I think now), and more importantly, how to correct a wrong node without deleting 6 miles of mapped road, or correct intersection road names without the complete collection of linked nodes taking a new name... (that is not ok for the moment).

More mapping tomorrow!
