I could certainly wander a few miles from home unsupervised. We played in woods, fields, along the shore and in building sites!
I think we’ve got to the stage where we need something like ‘nature play’. In my own school we have a fair collection of ‘loose materials’ some natural and some not. Logs, building site wooden pallets, plastic pipes and the likes. The pupils have a lot of fun.
