Hi Andy
I absolutely love the Nurburgring as went to watch the WEC 6 Hours there...loads better than Le Mans, not corporate, sit where you want, beer was only 5 euro not 9 euro at Le Mans...would definitely go there again.
Spa...what can I say! Probably my favourite circuit for all the reasons as Nurburgring but also a genuine grass-roots motorsport feel to the circuit. Loads of places to watch the action and if you're driving it....Look out for the turn at the top of Eau Rouge! One word of warning...it's located in the Ardennes which is renowned for it's own microclimate..when we first went in May, might as well have been January...incredibly cold so take some warm gear.
Keep us posted with your exploits
Cheers Trevor
