As many clubs do in the more southern parts of Europe, one could prob90 get cheaper avgas by importing it in 200 litre drums.
Of course this causes the airfield-based avgas facility to close, but that is OK for the "I am allright Jack" subsection of the GA "community"
Re Jersey, I am sorry to say this but frankly I hardly care. I've been there a number of times. The place has some pretty and memorable walks, especially the one round the lighthouse, but the rest of Jersey is a massive and pretty deprived council estate, with the rest of the population living in big houses tucked away, and smaller houses whose curtains are twitching H24. The genetic diversity and resulting culture is about 1% and you may as well visit the IOW or, if you find the IOW culture a bit overwhelming, the IOM
If Jersey ATC want to screw up the place, they are welcome to it.
