Between Sweden and Denmark there is a long bridge. Just before you come up on the bridge on the Danish side there is a tunnel maybe 2 miles long. Last year 14 F-cars of FOC - Sweden went to Copenhagen more or less for fun. On the way back home we went through the above mentioned tunnel and the sound these 14 cars made was just incredible. + 200 kph all 14 in a row............just fabulous. Too bad no one had a chance to record the sound. //B//
