Have to admit I bring a picnic (albeit ever weirder combinations of foodstuffs) as the price for a burger is a bit steep especially given the length of the queue.
Little Gransden do quite well with a BBQ manned by loadsa volunteers, prices not too steep either. Thinks... as the Mildenhall show looks like it's never on any more, how about inviting some of the squadrons there to bring along their BBQ gear, burgers, 'wet sauce' etc. You'd probably double the crowd with this alone and the Yanks would probably go crazy about an Olde English venue like OW. Just for the May show perhaps... and if they want to chuck in an MH-53 or F-15, well so be it
DeepC - perhaps you could hold the bucket for donations while Hairyplane provides the intimidation, famous as he is for freeloader-squashing expeditions?
