I wandered off without so much as a brief goodbye to TPR.
When I reached the pond I hid the DAB radio so that I could swim across the water rather than take the longer route along the path. It was a lovely day for a dip, and even the pond weed did not bother me.
When I returned later to collect the radio from its hiding place I discovered that it had been stolen. The park ranger offered me another one from lost property, but it was smaller than mine and I knew that TPR would be able to tell the difference.
