Monday, August 30:  Water Your Mind Movies @ Your Library presents “Back to the Beach” @ 7:00 pm.  This tribute to the 1960s Beach Party pictures brings back Frankie Avalon and Annette Funicello.  The two landlocked surfers return to the California sun with their wild kids. There are many gags about the earlier films  and cameos.   This is a genuinely smart and funny movie, although it helps to know the original films.  Rated PG.  (92 min.)
