NASA’s March 23 announcement of evidence of the past presence of “a body of gently flowing saltwater” on Mars is big news for America, and giant news for seafood fans. In January, Long John Silver’s offered to give America free Giant Shrimp if NASA found conclusive evidence of an ocean on Mars. To celebrate the success of NASA’s Mars Rover project, the company is going to give America free Giant Shrimp on Monday, May 10, 2004.
