...of traffic jam.

Last Wednesday, I was driving to Wacken Open Air - the World's biggest Heavy Metal Festival, situated near the village Wacken(http://informationfreeway.org/?lat=54.02362543046328&lon=9.37861261315626&zoom=14&layers=0B00F000) in the middle of nowhere in the German state of Schleswig-Holstein.
Unfortunately, there had been massive rain the days before and the campgrounds where not accessible for cars, leading to a temporary shutdown of the main entrance and thus a massive traffic jam from the Motorway 23 to the Village.
(Which was also fun, at least for those not having to drive, because most people just started the festival on the road :-) )

Anyhow, the Joke is: Friends of us, who started 8 hours later, managed to circumvent the jam because they met a local Festival employee at a motorway restaurant and followed him through some "secret" unclassified and track roads.
The result was that we all arrived at the main entrance simultaneously.

So, if there had been good OSM coverage of the area(there was nothing and commercial routing software also didn't help), maybe we could also have saved some hours and went to sleep before sunrise that day. ;-)

Apart from this, it was a great Festival - I'll be there again next year and hope there will be some more coverage by that time.
(I've added some local roads and tracks now, but they only cover the two main routes from and to Wacken)
