It's CITO season again and therefore time to collect that all important jpeg souvenir that makes our lives that little bit brighter. There is also the small matter of improving one of the many lovely green spaces of Sheffield that gets a bit spoiled by the actions of a small minority of the locals. We'll be picking the litter in and around the woods, so you can don your wellies and get in the stream for the full terrain experience or stick to the paths if you want to take it easy. As an added incentive Marky1981 has published a great new series in the valley if you haven't done it already. As usual gloves, tools and light refreshments will be provided, just bring appropriate clothing and footwear.
