What could possibly make you feel more mellow, posivibes about Brooklyn than doing yoga, for free, in Brooklyn Bridge Park this weekend? Flavorpill and Emblem Health have teamed up to offer free yoga on Harbor View Lawn with teachers Elena Brower and Aarona Pichinson and music by DJ Drez and violinist Hannah Thiem. Yoga starts at noon, but the doors are at 11am and the first 250 people who show up get free yoga mats and other goodies. The event is free, but you do need to RSVP here. Glorious fall weather, a gorgeous view of Manhattan and free yoga goodness? Namaste.
