Anyone have a contact for someone who runs one of the national potato
days,
please? (preferably the Hampshire one, but anyone from one of the others
would do)

I'm toying with the idea of arranging one (on a rather smaller scale) next
year, as we don't have anything anywhere within about 2 hours drive, which
seems silly.

Some indication about where to start and just how much hard work it would
entail would be good.

The Hampshire one is run by these people...

If the Hampshire one is anything to go by you will need a venue with a lot
of parking, some refreshments available, and most importantly, toilets. That
one started small and has snowballed, gets quite manic at times so choose a
venue that will allow you to grow, you don't want to have to move after a
couple of years. And don't forget the advertising, always key.
