My first succesfull upload of, I thought, one track turned out to be all active logs from Yosemity from the last three days. I still have to learn to rtfm.
To do: clean up the active log. After that check the OSM map if it is any good compared to my tracks and poi's.
The bad: I can't do that on my crappy laptop here in the states. This has to wait until I'm back in the Netherlands.
