They had that blue Alpine with the green nose (don't know much about the historics!) that races in the LM historics there last year - that was fun watching it trying to get around the tight twisty, hilly circuit and it sounded great reverberating off the buildings. The Porsche's were great to watch, really close racing.
It's a great weekend (and pretty cheap too), but this year's clashes with Silverstone, so I'll be there instead.
