As Pugwash says....it's more about the social aspect of the entertainment, having a beer, a chat with your mates and the general banter than a bike show.
As long as you're all tucked up in bed by midnight and snoozing gently.
Done quite a few memba rally's and used to take my lad to the tail end, but after that sham where they punted all the biker members out to elton hall, and when the marshals come round en-force to make us go to bed 'or pack up and leave' at midnight, I won't be camping with them again.
I was talking to a stall holder earlier today, he had two big tents next to HGB's and George Whites. He was saying he'd had a load of helmets stolen during sat night, tent was slashed and they'd just helped themselves, and he caught someone stealing during one of the days.
His biggest worry was how few people were there, especially considering how nice the weather was. he didn't think it will last much longer, so few stands, dealers, and less and less customers.
To be honest the showground isn't up to a biker rally these days, too close to housing, hence the early finish at night. If they considered moving it to somewhere like the Newark showground they might have a chance to develop it and save it, but can't see it somehow. A while back I had quite a chat with that Jane woman that runs the whole thing and she really wasn't receptive to any critcism, in fact she got really quite defensive about things. I really don't think she has a clue.
