Flipping flac

We went to the circus today, German-stylee.
They're called 'Flic flac' and although no animals are hurt (or even used) during the show, stretcher bearers are sometimes required...
This is a photo taken during the finale, three crazy motorbikes take it in turns to shoot up through through the stairwell, over the central ring and down a ramp on the other side. Of course they don't do this seated, that would be far too easy, they just about keep hold of the bike, by their bitten down finger nails I reckon.
A truly thrilling two hours.
