Some of the most relaxing & satisfying things I have ever done with a computer was spending hours updating OSM from fresh satellite images.

It was giddying to discover that Bermuda had great satellite images, but zero mapping and then a few hours later you'd literally put a well-known place like Bermuda "on the map" by drawing in most of the main roads, airport and so on. Great to see that others have built on this with detailed information.

Very fond memories.
