A few personal words on Groningen: I find Groningen very interesting for its different architecture,for its very busy and vivid city life and for its bicycle culture. There are only a few cars on the streets.The urban traffic is almost dominated by the cyclists. By the way, it is almost impossible taking a picture without a bike on it.
