There’s a glint in the trees between the Creatures hut and the Black Lake, and if you get close enough, you can see a large caravan shaped like a plump silver bullet. It glitters where sunlight reflects dappling patterns against the side of the vehicle. This is clearly where Cornish lives – a chair and table under the awning, laundry flapping from the line stretching between two trees, and his shaggy dog Brenda asleep under the steps.

Students are welcome to stop to play with the dog, but even better, Cornish has created some wading pools in the lake shallows behind his caravan, and they’re welcome to examine the wildlife, dip their feet in the water, or go for a careful swim. Take advantage while the weather is warm enough.
