There are more than one hundred giant heart sculptures in various public and private locations throughout the city of San Francisco. What better way to spend the year's most romantic weekend than racing to see who can find the most hearts in two hours? Teams of 2-6 people will fan out from Union Square, following clues and taking selfies in front of the hearts they find. It's a great way to see the city, notice things you might otherwise miss, get some exercise and just have a good time. What's not to "love" about an activity with so much heart behind it?
