[Talk-ca] Hiking trails - Is bad data better than no data?

[James Ewen]

I vehemently oppose including bad data in the OSM database. I only
insert the best possible data available into database.

If your GPS tracks are the best data available, then insert that into
the database. Should better data become available, then that should be
used to increase the accuracy of the trail data.

It's all in the way you look at it!
