This weekend I went down to the West Palm Beach area to celebrate my sister-in-laws graduation from FAU. My father-in-law noticed that his son's neighborhood was not completely mapped in either Bing or on Google. Bing is missing some streets, and Google is missing some street names. I pulled up OSM and the situation was even worse. No streets where mapped at all. Apparently this place was only built around two years ago.
Like a good OSMer, I began tracing the missing streets using the areal imagery. When I was done with that I downloaded the area into JOSM, loaded the kids into the car, and drove around, marking the names of the streets as we campused the neighborhood. When we got back we uploaded the edit, and now OSM has the only 100% mapping of the area.
I mapped some other missing streets, but there is no chance of me getting the chance to visit the areas to get street names, mostly because of time issues, but also, these are gated communities where I wouldn't be allowed in to anyways.
