Absolutely no worry Iain, I love this picture its really nice and fun. And this is a relaxed forum. My first intention was to suggest a direct contact with HVM, you and Alan do know those people very well. After that it came up to my mind that, for instance, Diogo Ferrao or others may be have cars/team based in UK. And yes, while writing I was wondering if it makes sense or… less sense!
Pau is really far from Calais or Dover and we all know that sometimes transportation can be a hassle.
If you go there, have fun and be safe!
