Possibly. Back in my youth (ca 1970) the residence of choice at Avon was the railway tunnels, a damp/cold and ghoulish place and one night my brother and I were woken by a terrible moaning approaching. The ghost turned out to be Tony Wilmot and Matt Peacock, Tony suffering from an impacted wisdom tooth. In the morning we went to leave and climbed over the rough wall near the end to find the resident tramp (might have been called Ted or was it Ted who had the tea van?) had sadly expired in the night.
The other favoured place to sleep was in the roof space above the tennis club toilets, (not in the toilets themselves) or nip up to the cave.
