Fiesta is one of Americas truly great festivals. It began as a way to honor the memory of the heroes of the Alamo and the Battle of San Jacinto. That commemoration still takes place. But over the past century and more, Fiesta has grown into a celebration of San Antonios rich and diverse cultures. Some 100 local nonprofit groups work in their communities year round to prepare for their Fiesta events. 2010 marks Fiestas 119th anniversary.
