This is beginning to sound like a plan. I've a friend who would be delighted to put a few people up for a night or two, I've got the caravan, and I'll look into somewhere to camp.
I'll have a word with the landlord of the Black, but I'm sure he'll be happy as long as he's selling beer, and they do a Sunday carvery.
We've 2 bank holidays in May, what about Whitsun?
