Bringing along all kinds of materials, reference books, postcards, photos and other misc. items the atmosphere is a sharing one. Having not had time to gather such items myself (it had been a busy day) I only had my trusty Edding pen to hand, but was soon supplied with a bird (of course!) ref book and a good slab of thin card.
Some photos (from Ben Harding) are below and keep an eye on their blog for information about the next one.
