Q: There is no food I enjoy more than ice cream. I'm not sure I have a favorite, but I really like rocky road. If you think about it, rocky road is an unusual name for an ice cream flavor. Do you know the story behind the name? -- T.L., Waukesha, Wis.

A: In 1928, ice cream maker William Dreyer and candy maker Joseph Edy founded a small ice cream factory in Oakland, Calif. The following year, Dreyer added walnuts (which were later replaced by almonds) and pieces of marshmallow to chocolate ice cream to create a new flavor. Since the nation had just experienced the stock market crash of 1929 and hard times were ahead, the name rocky road was chosen to help put a smile on the faces of consumers. According to the folks at Dreyer's Grand Ice Cream, rocky road became America's first blockbuster flavor and remains one of the best-selling flavors of all time.

Q: The movie "The Great Escape" is one of my all-time favorites. I know the film was based on an actual prison break during World War II. When and where did the escape occur? -- L.I.D., Daytona, Fla.

A: The escape took 600 men more than a year to plan. The prison camp was Stalag Luft III, located in what is now Poland. The escape occurred on March 24, 1944.

While most of the film is based on true events, two events were fabricated: Steve McQueen's motorcycle scenes and the theft of a German airplane by Hendley (James Garner) and Blythe (Donald Pleasence).

Paul Brickhill (1916-1991) wrote the book on which the film is based. He piloted a Spitfire aircraft that was shot down over Tunisia in March 1943. He was taken to Stalag Luft III, where he assisted in the escape preparations.
