I certainly do . Though perhaps not with great accuracy - weren't the clothes a sort of gingery brown and involved plus four trousers ? Or has my mind invented that ?
I do remember them being very strict - cycling only allowed on the main road round the edge of the park .
Yes it was a rough material and in a gingery brown too. There was a lady park keeper who wore a round brimmed hat who was quite stout and very scary to us children. They used to have small wooden huts for the park keepers which were dotted around the park. Thanks for finding the photo. All good memories!
