It's the Low Moor allotments in York, although I think well probably have the supper itself in a local 'hall'. I think it's the first year this has been done, I'm fairly new to the committee, but I know we're trying to encourage more community spirit.
Last year we built a French boules pitch on site, which we're encouraging people to use as a social venue.
Thanks for all the suggestions. I think mid Sept might be the best option, people should have finished their summer holidays by then too. I'm just hoping that everyone doesn't decide to use the supper as an opportunity to rid themselves of excess courgettes/marrows!
