... is also a "leading light".
BBC actually handles the service registrations which enlarges the preposterousness of it all. How crazy can it be that RATP (the Paris bus and metro operator and owner of BBC) is technically running buses to an unoccupied isolated village on one day a year with vehicles supplied by London bus companies?
Anyway, thanks to two kind contributors, fbb can publish a series of pictures of the weirdness of this excellent day.
First, a batch of routemasters, two old and one new, the latter better known as a Borismaster.
Then there was Ensignbus's open topper ...
... and a multicoloured Borismaster.
London Buses, of course, now have to be completely red - except when they aren't!
Also at Imber was the London Northern routemaster coach.
It was all slightly surreal.
The short answer is almost nothing! As Imber is normally closed to the public there are no shops, no permanent toilets and no mobile phone reception. We therefore strongly recommend that you prepare for this before you board the bus (the nearest public toilets will be at Warminster Station and alongside Warminster Central Car Park).
Thanks to John and Northampton correspondent Alan for loadsa stuff.
