You want to see some great art, but you don't want to spend a beautiful summer day inside a museum? I hear that! And I might have the perfect solution for you.The Love Letter Train Tour in Philadelphia. I referenced it in "For What I Want, I Can Wait" last year, and I finally took the full tour last weekend.As I knew it would be, the tour was an incredibly unique experience.First, we hopped the El train at Market East Station and headed West. Once we hit 45th street, a whopping fifty murals by Stephen Powers (aka "ESPO") started popping up one by one, all within eighteen blocks. It was almost like a rapid-fire game of "I spy." And each mural was more creative and colorful than the next.Check out some of my favorites below: "Your everafter is all I'm after." (with the greatest view of Philly I've ever seen) "Miss you too often not to love you." (note how Powers was sure to never paint over any original building signage. Cool.) "Open your eyes I see the sunrise." "This heart is safe for valuables" (above Philadelphia Savings Fund)What a beautiful, upbeat and positive gift Stephen Powers gave to West Philadelphia. I highly recommend you check it out!
