(Thomas Burr | The Salt Lake Tribune) Misa Morreall chats with friends at her 1990s-themed birthday party in Arlington, Va., in a neighborhood dubbed "Little Provo" for the scores of young Mormons who call it home. Morreall, a Brigham Young University graduate who is from New York, celebrated her birthday among her fellow faithful with hip-hop music from the ’90s, an ice cream sundae bar and slap bracelets.
