One evening this summer, Mel Packer opened the front door of his home in Point Breeze to a young man wearing a bicycle helmet. His name was John Pena, and in his hand was a letter, handwritten by two friends of Mr. Packer's 17-year-old daughter, Rosa.

It was one of the few evening rounds all summer that Mr. Pena had cycled without his partner, Ally Reeves. The Carnegie-Mellon University art students, in a collaborative performance-art project, have delivered more than 300 letters as the self-styled "Pittsburgh Pedal Express."

The letter to Rosa Packer earned Mr. Pena an invitation to share dinner with the Packer family.

It was a highlight among many stories and expressions of delight the pair has collected on their magical mystery tour of the city. But the best story, and the most delight, has been their own.

Third-year graduate students, both 26, they decided last spring to team up on an art project. They are both letter writers, they use bicycles for transportation and they fancy the alternative gesture.
