Thanks both -I have an awkward feeling that I have had this clue before and someone on this site answered it . Perhaps I didn't come across 'rec' for 'park' when much younger .
Glad we could help. I'd never heard of rec = park until the people in Coronation Street talked about going to the 'red rec'! This was many years ago, but after that it popped up in a few puzzles and stuck in my mind.
