There is a steep bank from the path in the park up to the pavement where it seems people finish their drinks/sweets/crisps and chuck them over the fence. In winter it becomes apparent how much litter there is there. So, today I decided to tackle it and got a great workout - looking for the next hand or foothold, manoeuvring myself and the bag around sticky out branches and brambles. It was a bit like bouldering! I do wish the bottle deposit-return system was still in effect. I think it would make a huge difference.
