Hi Puffin, welcome to our forum!! Have you checked out the events on our 2010 calendar? I have been busy searching for relevant gardening events so there might be a suitable potato day listed. As it's only the start of January there will be more events and hopefully potato days to add to the calendar when societies confirm their 2010 dates.
