Den of Iniquity?

We’ve passed this amazing den in Rivey Woods several times. Someone has obviously put a lot of effort and time into creating it. Apart from a carrier bag of snack wrappers there were no signs of life.
It’s been a lovely day but we couldn’t go in the garden as the tree surgeons were here until 3.30.
I’ve made a half hearted attempt at starting my school reports. It’s very difficult when you haven’t seen the children for 7 weeks!
