Google Sightseeing: Oktoberfest
After having found that Google Maps finally has some high-res satellite images for some small parts of germany (including my home), I figured that the images are probably from around september 2004. Bingo:
Oktoberfest tents being set up
Too bad they didn’t take shots when Oktoberfest is on - there would be thousands of people on the streets, and even more hidden in the tents.
