The happy folk of Friends with You have descended upon New York City and are shooting rainbow trails wherever they travel. Today was overcast, but there was plenty of color and peals of laughter at Rainbow City—the inflatable wonderland at the end of the High Line. Go visit and have a ball. Try your best to avoid the magnetic pull of their kiosk brimming with plastic toys, totes and enamel badges. My sole complaint is that the jumping rooms (inside the giant happy shrooms) are only for kids. They should have one just for adults (or at least for a few hours), because we want to play too!
