Philadelphia is a great escape for me because it is an easy train ride from NYC, and most of my favorite destinations can be reached on foot. My favorite activities here include browsing among the incredible art collections at The Barnes Foundation; checking out the annual springtime Flower Show at the Convention Center; strolling the city to see the pocket gardens, murals, and public art installations; and stopping for some treats at Reading Terminal Market.
