I'm very happy with osm. I cycled in spain and osm appeared to be very useful. A pity that I did not find the elevation files before my holydays.
Also here in the netherland I use openfietsmap and it's very useful. I can say the same about Belgium.
Well last but not least: short holyday in Lissabon. I took my Garmin with me. Fantastic, thanks to openstreetmap I found a bicycle rental company (bikeiberia).
Thanks for the good work.
Cheers,
Peter
