Does anyone else thinks there's a shortage of German fans. The Danes and the Brits seem far more visible
Yes there is; a few years ago, I invited a good friend and work colleague from Germany to come along for the week at Le Mans. He brought 2 of his friends along as well, drove from Munich on the Thursday.
On the face of it, they said that they enjoyed the weekend but did not get the atmosphere in the camp site and all that goes on. It just did not appeal to them

So much so, that they left early on the Sunday to drive back and ended up Disneyland Paris

on route back said now ex friend phoned up and said he'll stick to watching F1....................
Maybe it's also the case that the Germans have the Ring 24 hours a few weeks before LM24 which they have made their own.
