Went for a drive in the Blue Mountains this morning - picked a random bush track at the end of a street and went for a walk. After a few km's of serene bush, I was pleasantly surprised to come across a decent sized dam - it's now a feature in OSM. I bet it's not shown on any other street map!

I've had a Qstarz BT-Q1000P for a week now and I've walked most of my local neighborhood. I'll probably go over it again with a digital camera and map all the stop signs, pedestrian crossings, walkways, bridges, landmarks etc. that I missed the first time around.
