Be Free Floating is tucked away in a row house on the very western corner of Pratt Street. You’ll know you’re there when you see the ornate gate flung open onto tall wooden doors, mosaics of glass lining the front of the building. Step inside and Twig Harper, proprietor and guide, will show you to the tank room. Close the hatch and it’s just you with yourself floating in salt water for an hour, and if you’re patient, the deepest relaxation you’ll find without a prescription or a dealer.
