7X7SF covers this heart-warming story of San Francisco groom-to-be Jason Fordley who hired artist Andres Amador to create this amazing large-scale sand mural wedding proposal at Ocean Beach for his girlfriend Kelly Riplinger. Needless to say, she said YES!
From the article:

Here’s how it all went down: Several years ago, Jason and Kelly were enjoying a picnic of Thai take-out on Ocean Beach when they noticed Amador creating a mural in the sand. “It was one of our first dates in San Francisco and it was just so cool,” says Kelly. “We took a bunch of photos and it was a great memory.” Three years later, Jason tracked down the artist via the Internet and asked him to create a wedding proposal sand mural on February 12. The artist conceptualized the design and directed a handful of the couple’s friends in raking it into Ocean Beach. It took them, according to Amador, about an hour and a half to get the job done; then everyone took cover on the sidewalk above the rocks.
