So, yestreday I did a road trip round Rural france, with the planned side effect of expanding the coverage. Sadly my freshly installed 'Event Logger' locked up the tomtom and post hard reboot only had a small fraction of the 600 miles I did. Oh, and that fraction won't even open in josm (not well formed) -- Hopefully the latter is just beacuse of a missing /trkseg /trk /gpx combo
