There was a movie about a young girl that is dying - she has a list of things she wants to do before she dies - one is being in 2 places at one time and her boyfriend or husband has her stand on a State line of NC & SC - she also wants to get married in the church where her parents were married.

A Walk to Remember (http://www.imdb.com/title/tt0281358/)

I can never remember this title either... love this movie!!
