Frisbee Golf, or Disc Golf, is played a lot like regular golf, except you use frisbees or discs rather than golf balls, and you throw the frisbees into standing cages or goals, rather than hitting balls into a golf hole.  Most cities have a Disc Golf course set up for the public where they can go play for free.  It is usually just some city park.  There is a course similar to a golf course, where you go from one hole to the next throwing your frisbee and then picking it up and throwing it again from where it landed.  There are different pars for the different holes and there are different kinds of discs you can use to get greater or lesser distance and more or less control.
