Its not just exotica that goes around there. I was last there in April and I kid you not , I was doing 145mph+ down Flugplatz and had a big brown pants moment passing a tour bus loaded with tourist! Previous times I was there, there was a Citroen Berlingo with roof rack full of ladders doing a lap around the ring! Its unbelievable what car/bike/bus/truck people take around there.
