Combining photography and OSM seems to work well.

There were several marks in Holladay and Mill Creek that contradicted the photos I had taken earlier in the day. Having photographic evidence in my hand gave me the confidence to make the corrections.

The danger of photography is that it becomes very tempting to add a triviality to a map simply because I have a good photo. Fortunately, I am good at avoiding temptation.
