Jane,
We have to pay for the hall, speakers, cookery demonstrator etc and so no one (except for helpers) gets in free!
The cost is £2 per addult this and all details including a map and our variety list are at
www.hhdra.org.uk/potatoday.htm
We've just managed to get a small quantity of Sarpo Mira and Sarpo Axona
PS do you want to help for a couple of hours??
