Got a gps in November 2007 and have traced lots of roads on occasional trips in Finland. There's still lots to do in Helsinki, too, with ground surveys.

Most likely I have track logs to justify my edits - the aerial images can and do have some offset.
Of the oldest tracks I have uploaded the ones with their name ending in a _2 are simplified versions and I have the originals.
