In the space of 24 hours I met two Europeans with Bonneville Red hats here in the UK. (The second I met has a blue hat too).
First it was Pork Pie then it was Fabio Montani. Both gained their records with wheeldriven cars of course. Because there have only been 16 Europeans (thanks for that statistic PP) in the Bonneville 2 Club, since Segrave started this 200+ record breaking, that's a high percentage of the living members.
