That was a lot of recognisable pics being Dutch and now living in Australia. The fire truck is DELWP (State of Victoria) They have quite a fleet of Mog's.
The pictures from the Netherlands speak for themselves. I raced on the old F1 track btw, it is a nice track in the dunes but at that time it had a one corner that was very motorbike unfriendly (as in, if you came of the bike, you would be in the wall immediately) so I preferred the TT track in Assen for riding as it was MotoGP sanctioned and very safe. Maybe that corner has changed now? I do not follow F1 anymore so no clue how it looks like now.
