Had to solve this one twice because my machine crashed while saving my snapshot!
I had immediately created a placemark but I guess they only get saved when you close Google Earth? Feature suggestion for Google: save placemarks immediately upon creation or modification. Oh, and how come I only get the content emails two days after the first people are already posting solutions? Doesn't seem quite fair. OTOH, it's a fun challenge and I'm getting into it, so thanks for all the fun!
