There is a wonderful & fun art installation in Union Square in San Francisco. Every year, popular artist come in and paint hearts that decorate the corners of Union Square. At the end of the year the hearts are auctioned off with proceeds going to the San Francisco General Hospital.
This is a must see, and really hard to miss. Unfortunately, construction blocked off one of the hearts, but we got some great images of the other three!
Fun fact- this is all based off the popular song by Tony Bennett- "I Left my Heart in San Francisco"!
