Where's Retford?

On a trip to Rufford Park on a lovely spring day, it was rather annoying to notice that at the new A1/A57/A614 Apleyhead junction, between Retford and Worksop (and the most direct route into the area from Nottingham) there are no directions to Retford! Do we not exist? Come on highway agencies a little help to get people into the town would be helpful.
