In honor of National Pig Day, the Lehigh Valley Iron Pigs, the new triple-A affiliate of the Philadelphia Phillies, are putting their single-game tickets on sale today. Though not an official holiday, March 1 is National Pig Day. It was started in 1972 by a Texas art teacher named Ellen Staly, who wanted to acknowledge the intelligence and good-nature of the domesticated pig. The day is now celebrated with a variety of events at zoos around the country. The Iron Pigs will also be having a day of piggy events geared to children and adults alike. Sounds like fun except for the pig roast. Really, could they not have had a fish fry?
