This is like golf, except it's played with Frisbees. A course, laid out at Morley Field in Balboa Park, is open seven days a week from dawn to dusk. Frisbees are available to rent for a small fee, and there's also a small fee for using the course on a first-come, first-served basis. Rules are posted. Directions to the field are available from the Balboa Park Disc Golf Course (619/692-3607. www.morleyfield.com).
