Got this fun e-mail from the people at the city's Mural Arts Program, about a surprise marriage proposal the program's folks helped arrange (a sweet video follows):
"A Canadian couple, Todd and Meaghan, learned about the Mural Arts Program's 'Love Letter Tour' and coordinated an extended layover in Philadelphia (en route to Paris) to experience this wildly popular tour.
"Todd contacted the Mural Arts tour office to let them know he wanted to propose to Meaghan on the tour, and the Mural Arts Program offered a clever idea in making his marriage proposal extra special.
"This video is a result of Mural Arts Program's partnership with The University of Pennsylvania - Penn Singers Light Opera Company and Penn Glee Club. We're excited to share with you the biggest surprise of Meaghan's life!"
