The first morning of the workshop, I think we became part of a very exclusive club that actually saw you sporting a sparkling clean lab coat! By the last day we all agreed we were tired but happy, and I think very excited to have had the opportunity to learn from and talk with you, Mark and so many others. I really like that the 'lunch group' seemed to wander down to the darkroom at different times to see how we were doing. Thanks to you, Mark and all that helped share their knowledge and experience but most of all your joy of what you shared with us.
