Peanuts Halloween 1977: I want to see the "Great Grape" when he arrives

The Great Pumpkin story line in 1977 took place mostly AFTER Halloween.  The first strip was on Sunday, October 30, when Snoopy briefly joined Linus in the pumpkin patch.  On Halloween, Marcie, needing something to believe in, waited with Linus to see the "Great Grape", but her parents later deprogrammed her.
