The only dream guest I never got a chance to interview was Culp . I ' ve written to him quite a few times extending an invitation , I even tried reaching him through his grandson . But I never heard back . Some have said he does n't like to do " those kinds of things " but here he was at the Hero Tribute .
According to the above context, answer the following question.
Why did the narrator reach out to the grandson ?


To get a chance to talk to Culp .
