I've lived in Worthing for 4 years now and I think it know it pretty well. It's very small and compact so I know the central part well, not as sure about the outskirts.
I find it funny when I ask people if their parents/family members live locally or close by. I had someone answer - Oh no, no my parents don't live locally, they live in Findon. Well, Findon is a part of Worthing! It's in the Northern outskirts of Worthing. It makes me laugh so much, the different perceptions of long distance here.
