This one in San Francisco:

[Christina Wu and Chris Little] got to know each other four years ago waiting for and riding the 31AX-Balboa express bus to their jobs in downtown San Francisco. Today, they will be getting married in a Muni-themed ceremony.

[…]

[Wu] and Little used to catch the morning bus at the same Richmond District corner at 25th Avenue and Balboa Street, and after a couple of months of noticing each other, he struck up a conversation before the express arrived.

“Muni wasn’t my Match.com – at least not by design,” said Little, 39, who works in Internet advertising sales. “But if I drove, I probably wouldn’t have met Christina.”
